Additional OS/2 API functions implemented in DOSCALL1.DLL:
|
|
- File handling (64-bit functions available in WSeB/MCP/eCS and
|
|
protected access to file handles as available in OS/2 2.1+)
|
|
- Certain SMP related functions for querying and setting status
|
|
of processors and thread and system affinity (available
|
|
in SMP-ready versions of OS/2 kernels)
|
|
- Support for working with extended LIBPATH (available in
|
|
OS/2 Warp 4.0 and higher).
|
|
Availability of individual functions is checked dynamically during
|
|
initialization and fake (simulated) functions are used if running
|
|
under an OS/2 version not providing the respective functionality.

Bit 1 (Atomic) means request for atomic locking - if the bit is set

and the lock range is equal to the unlock range, an atomic lock occurs.
|
|
If this bit is set to 1 and the lock range is not equal to the unlock
|
|
range, an error is returned. If this bit is set to 0, then the lock
|
|
may or may not occur atomically with the unlock.
|
|
Bit 0 (Share) defines the type of access that other processes may have
|
|
to the file range that is being locked. If this bit is set to 0
|
|
(default), other processes have no access to the locked file range.
|
|
The current process has exclusive access to the locked file range,
|
|
which must not overlap any other locked file range. If this bit is set
|
|
to 1, the current process and other processes have shared read only
|
|
access to the locked file range. A file range with shared access may

Remarks:
|
|
DosProtectSetFileLocksL allows a process to lock and unlock a range in a file.
|
|
The time during which a file range is locked should be short.
|
|
|
|
If the lock and unlock ranges are both zero, ERROR_LOCK_VIOLATION is returned
|
|
to the caller.
|
|
|
|
If you only want to lock a file range, set the unlock file offset and the
|
|
unlock range length to zero.
|
|
|
|
If you only want to unlock a file range, set the lock file offset and the lock
|
|
range length to zero.
|
|
|
|
When the Atomic bit of flags is set to 0, and DosProtectSetFileLocksL specifies
|
|
a lock operation and an unlock operation, the unlock operation occurs first,
|
|
and then the lock operation is performed. If an error occurs during the unlock
|
|
operation, an error code is returned and the lock operation is not performed.
|
|
If an error occurs during the lock operation, an error code is returned and the
|
|
unlock remains in effect if it was successful.
|
|
|
|
The lock operation is atomic when all of these conditions are met:
|
|
- The Atomic bit is set to 1 in flags
|
|
- The unlock range is the same as the lock range
|
|
- The process has shared access to the file range, and has requested exclusive
|
|
access to it; or the process has exclusive access to the file range, and has
|
|
requested shared access to it.
|
|
|
|
Some file system drivers (FSDs) may not support atomic lock operations.
|
|
Versions of the operating system prior to OS/2 Version 2.00 do not support
|
|
atomic lock operations. If the application receives the error code
|
|
ERROR_ATOMIC_LOCK_NOT_SUPPORTED, the application should unlock the file range
|
|
and then lock it using a non-atomic operation (with the atomic bit set to 0
|
|
in Flags). The application should also refresh its internal buffers before
|
|
making any changes to the file.
|
|
|
|
If you issue DosProtectClose to close a file with locks still in effect,
|
|
the locks are released in no defined sequence.
|
|
|
|
If you end a process with a file open, and you have locks in effect in that
|
|
file, the file is closed and the locks are released in no defined sequence.
|
|
|
|
The locked range can be anywhere in the logical file. Locking beyond the end
|
|
of the file is not an error. A file range to be locked exclusively must first
|
|
be cleared of any locked file sub-ranges or overlapping locked file ranges.
|
|
|
|
If you repeat DosProtectSetFileLocksL for the same file handle and file range,
|
|
then you duplicate access to the file range. Access to locked file ranges
|
|
is not duplicated across DosExecPgm. The proper method of using locks is
|
|
to attempt to lock the file range, and to examine the return value.
|
|
|
|
The following table shows the level of access granted when the accessed file
|
|
range is locked with an exclusive lock or a shared lock. Owner refers to
|
|
a process that owns the lock. Non-owner refers to a process that does not own
|
|
the lock.

If only locking is specified, DosProtectSetFileLocksL locks the specified file
|
|
range using Lock. If the lock operation cannot be accomplished, an error is
|
|
returned, and the file range is not locked.
|
|
|
|
After the lock request is processed, a file range can be unlocked using the
|
|
Unlock parameter of another DosProtectSetFileLocksL request. If unlocking
|
|
cannot be accomplished, an error is returned.
|
|
|
|
Instead of denying read/write access to an entire file by specifying access
|
|
and sharing modes with DosProtectOpenL requests, a process attempts to lock
|
|
only the range needed for read/write access and examines the error code
|
|
returned.
|
|
|
|
Once a specified file range is locked exclusively, read and write access by
|
|
another process is denied until the file range is unlocked. If both unlocking
|
|
and locking are specified by DosProtectSetFileLocksL, the unlocking operation
|
|
is performed first, then locking is done.

|
accomplished, an error is returned.
|
|
|
|
Instead of denying read/write access to an entire file by specifying access and
|
|
sharing modes with DosOpenL requests, a process attempts to lock only the range
|
|
needed for read/write access and examines the error code returned.
|
|
|
|
Once a specified file range is locked exclusively, read and write access by
|
|
another process is denied until the file range is unlocked. If both unlocking
|
|
and locking are specified by DosSetFileLocksL, the unlocking operation is
|
|
performed first, then locking is done.

existing file and returns a protected file handle. An open file can have
|
|
extended attributes.
|

|
|
Parameters:
|
|
FileName = ASCIIZ path name of the file or device to be opened.
|
|
Handle = handle for the file is returned here.

|
|
it is one of the following values:
|
|
1 FILE_EXISTED - file already existed.
|
|
2 FILE_CREATED - file was created.
|
|
3 FILE_TRUNCATED - file existed and was changed to a given size (file was

replaced).
|
|
InitSize = new logical size of the file (end of data, EOD), in bytes; this
|
|
parameter is significant only when creating a new file or replacing

Attrib = file attributes; this parameter contains the following bit fields:
|
|
Bits Description
|
|
|
|
31..6 - reserved, must be 0.
|
|
5 FILE_ARCHIVED (0x00000020) - file has been archived.
|
|
4 FILE_DIRECTORY (0x00000010) - file is a subdirectory.
|
|
3 - reserved, must be 0.
|
|
2 FILE_SYSTEM (0x00000004) - file is a system file.
|
|
1 FILE_HIDDEN (0x00000002) - file is hidden and does not appear in
|
|
a directory listing.
|
|
0 FILE_READONLY (0x00000001) - file can be read from, but not written
|
|
to.
|
|
0 FILE_NORMAL (0x00000000) - file can be read from or written to.
|
|
|
|
File attributes apply only if the file is created. These bits may be set
|
|
individually or in combination. For example, an attribute value of 0x00000021
|
|
(bits 5 and 0 set to 1) indicates a read-only file that has been archived.
|
|
|
|
OpenFlags = the action to be taken depending on whether the file exists or
|
|
does not exist. This parameter contains the following bit fields:
|
|
Bits Description
|
|
31..8 - reserved, must be 0.
|
|
7..4 - the following flags apply if the file does not exist:
|
|
0000 OPEN_ACTION_FAIL_IF_NEW
|
|
Open an existing file; fail if the file does not exist.
|
|
0001 OPEN_ACTION_CREATE_IF_NEW
|
|
Create the file if the file does not exist.
|
|
3..0 The following flags apply if the file does not exist:
|
|
0000 OPEN_ACTION_FAIL_IF_EXISTS
|
|
Open the file; fail if the file already exists.
|
|
0001 OPEN_ACTION_OPEN_IF_EXISTS
|
|
Open the file if it already exists.
|
|
0010 OPEN_ACTION_REPLACE_IF_EXISTS
|
|
Replace the file if it already exists.
|
|
|
|
OpenMode = the mode of the open function. This parameter contains the
|
|
following bit fields:
|
|
Bits Description
|
|
31 - reserved, must be zero.
|
|
30 OPEN_FLAGS_PROTECTED_HANDLE (0x40000000) - protected file handle flag.
|
|
0 - unprotected Handle
|
|
1 - protected Handle
|
|
Protected handle requires the FileHandleLockID to be specified on subsequent
|
|
DosProtectxxxx calls.
|
|
|
|
Unprotected handle requires the FileHandleLockID value to be specified as
|
|
zero on subsequent DosProtectxxxx calls. An unprotected handle may be used
|
|
with the unprotected calls such as DosRead and DosWrite.
|
|
|
|
29 OPEN_SHARE_DENYLEGACY (0x10000000)
|
|
Deny read/write access by the DosOpen command:
|
|
0 - allow read/write access by the DosOpen command.
|
|
1 - deny read/write access by the DosOpen command.
|
|
A file opened by DosOpenL will not be allowed to grow larger than 2GB while
|
|
that same file is open via a legacy DosOpen call. Setting this bit to 1 will
|
|
prevent access by the obsolete DosOpen API and ensure that no error will
|
|
occur when growing the file.
|
|
28..16 - reserved, must be zero.
|
|
15 OPEN_FLAGS_DASD (0x00008000)
|
|
Direct Open flag:
|
|
0 - FileName represents a file to be opened normally.
|
|
1 - FileName is drive (such as C or A), and represents a mounted
|
|
disk or diskette volume to be opened for direct access.
|
|
14 OPEN_FLAGS_WRITE_THROUGH (0x00004000)
|
|
Write-Through flag:
|
|
0 - writes to the file may go through the file-system driver's
|
|
cache; the file-system driver writes the sectors when the
|
|
cache is full or the file is closed.
|
|
1 - writes to the file may go through the file-system driver's
|
|
cache, but the sectors are written (the actual file I/O
|
|
operation is completed) before a synchronous write call
|
|
returns. This state of the file defines it as a synchronous
|
|
file. For synchronous files, this bit must be set, because the
|
|
data must be written to the medium for synchronous write
|
|
operations.
|
|
This bit flag is not inherited by child processes.
|
|
13 OPEN_FLAGS_FAIL_ON_ERROR (0x00002000)
|
|
Fail-Errors flag. Media I/O errors are handled as follows:
|
|
0 - reported through the system critical-error handler.
|
|
1 - reported directly to the caller by way of a return code.
|
|
Media I/O errors generated through Category 08h Logical Disk Control IOCtl
|
|
Commands always get reported directly to the caller by way of return code.
|
|
The Fail-Errors function applies only to non-IOCtl handle-based file I/O
|
|
calls.
|
|
|
|
This flag bit is not inherited by child processes.
|
|
|
|
12 OPEN_FLAGS_NO_CACHE (0x00001000)
|
|
No-Cache/Cache flag:
|
|
0 - the file-system driver should place data from I/O operations
|
|
into its cache.
|
|
1 - I/O operations to the file need not be done through the
|
|
file-system driver's cache.
|
|
The setting of this bit determines whether file-system drivers should place
|
|
data into the cache. Like the write-through bit, this is a per-handle bit,
|
|
and is not inherited by child processes.
|
|
11 - reserved; must be 0.
|
|
10..8 - the locality of reference flags contain information about how the
|
|
application is to get access to the file. The values are as
|
|
follows:
|
|
000 OPEN_FLAGS_NO_LOCALITY (0x00000000)
|
|
No locality known.
|
|
001 OPEN_FLAGS_SEQUENTIAL (0x00000100)
|
|
Mainly sequential access.
|
|
010 OPEN_FLAGS_RANDOM (0x00000200)
|
|
Mainly random access.
|
|
011 OPEN_FLAGS_RANDOMSEQUENTIAL (0x00000300)
|
|
Random with some locality.
|
|
7 OPEN_FLAGS_NOINHERIT (0x00000080)
|
|
Inheritance flag:
|
|
0 - file handle is inherited by a process created from a call to
|
|
DosExecPgm.
|
|
1 - file handle is private to the current process.
|
|
This bit is not inherited by child processes.
|
|
6..4 Sharing Mode flags; this field defines any restrictions to file
|
|
access placed by the caller on other processes. The values are as
|
|
follows:
|
|
001 OPEN_SHARE_DENYREADWRITE (0x00000010)
|
|
Deny read write access.
|
|
010 OPEN_SHARE_DENYWRITE (0x00000020)
|
|
Deny write access.
|
|
011 OPEN_SHARE_DENYREAD (0x00000030)
|
|
Deny read access.
|
|
100 OPEN_SHARE_DENYNONE (0x00000040)
|
|
Deny neither read nor write access (deny none).
|
|
Any other value is invalid.
|
|
3 Reserved; must be 0.
|
|
2..0 Access-Mode flags. This field defines the file access required by the
|
|
caller. The values are as follows:
|
|
000 OPEN_ACCESS_READONLY (0x00000000)
|
|
Read-only access
|
|
001 OPEN_ACCESS_WRITEONLY (0x00000001)
|
|
Write-only access
|
|
010 OPEN_ACCESS_READWRITE (0x00000002)
|
|
Read/write access.
|
|
Any other value is invalid, as are any other combinations.
|
|
|
|
File sharing requires the cooperation of sharing processes. This cooperation is
|
|
communicated through sharing and access modes. Any sharing restrictions placed
|
|
on a file opened by a process are removed when the process closes the file with
|
|
a DosClose request.
|
|
|
|
Sharing Mode:
|
|
Specifies the type of file access that other processes may have. For example,
|
|
if other processes can continue to read the file while your process is
|
|
operating on it, specify Deny Write. The sharing mode prevents other processes
|
|
from writing to the file but still allows them to read it.
|
|
|
|
Access Mode:
|
|
Specifies the type of file access (access mode) needed by your process. For
|
|
example, if your process requires read/write access, and another process has
|
|
already opened the file with a sharing mode of Deny None, your DosProtectOpenL
|
|
request succeeds. However, if the file is open with a sharing mode of Deny
|
|
Write, the process is denied access.
|
|
|
|
If the file is inherited by a child process, all sharing and access
|
|
restrictions also are inherited.
|
|
|
|
If an open file handle is duplicated by a call to DosDupHandle, all sharing and
|
|
access restrictions also are duplicated.
|
|
|
|
EA = pointer to an extended attribute buffer. The address of the
|
|
extended-attribute buffer, which contains an EAOP2 structure. The
|
|
fpFEA2List field in the EAOP2 structure points to a data area where the
|
|
relevant FEA2 list is to be found. The fpGEA2List and oError fields are
|
|
ignored.
|
|
Output fpGEA2List and fpFEA2List are unchanged. The area that fpFEA2List points
|
|
to is unchanged. If an error occurred during the set, oError is the offset of
|
|
the FEA2 entry where the error occurred. The return code from DosProtectOpenL
|
|
is the error code for that error condition. If no error occurred, oError is
|
|
undefined.
|
|
|
|
EA is nil, then no extended attributes are defined for the file. If extended
|
|
attributes are not to be defined or modified, the pointer EA must be set to
|
|
nil.

|
|
|
|
Remarks:
|
|
A successful DosProtectOpenL request returns a handle and a 32-bit LockID for
|
|
accessing the file. The read/write pointer is set at the first byte of the
|
|
file. The position of the pointer can be changed with DosProtectSetFilePtrL or
|
|
by read and write operations on the file.
|
|
|
|
The file s date and time can be queried with DosProtectQueryFileInfo. They are
|
|
set with DosProtectSetFileInfo.
|
|
|
|
The read-only attribute of a file can be set with the ATTRIB command.
|
|
|
|
ulAttribute cannot be set to Volume Label. To set volume-label information,
|
|
issue DosProtectSetFileInfo with a logical drive number. Volume labels cannot
|
|
be opened.
|
|
|
|
InitSize affects the size of the file only when the file is new or is
|
|
a replacement. If an existing file is opened, cbFile is ignored. To change the
|
|
size of the existing file, issue DosProtectSetFileSizeL.
|
|
|
|
The value in InitSize is a recommended size. If the full size cannot be
|
|
allocated, the open request may still succeed. The file system makes
|
|
a reasonable attempt to allocate the new size in an area that is as nearly
|
|
contiguous as possible on the medium. When the file size is extended, the
|
|
values of the new bytes are undefined.
|
|
|
|
The Direct Open bit provides direct access to an entire disk or diskette
|
|
volume, independent of the file system. This mode of opening the volume that is
|
|
currently on the drive returns a handle to the calling function; the handle
|
|
represents the logical volume as a single file. The calling function specifies
|
|
this handle with a DosDevIOCtl Category 8, DSK_LOCKDRIVE request to prevent
|
|
other processes from accessing the logical volume. When you are finished using
|
|
the logical volume, issue a DosDevIOCtl Category 8, DSK_UNLOCKDRIVE request to
|
|
allow other processes to access the logical volume.
|
|
|
|
The file-handle state bits can be set by DosProtectOpenL and
|
|
DosProtectSetFHState. An application can query the file-handle state bits, as
|
|
well as the rest of the Open Mode field, by issuing DosProtectQueryFHState.
|
|
|
|
You can use an TEAOP2 structure to set extended attributes in EA when creating
|
|
a file, replacing an existing file, or truncating an existing file. No extended
|
|
attributes are set when an existing file is just opened.
|
|
|
|
A replacement operation is logically equivalent to atomically deleting and
|
|
re-creating the file. This means that any extended attributes associated with
|
|
the file also are deleted before the file is re-created.
|
|
|
|
The FileHandleLockID returned is required on each of the DosProtectxxx
|
|
functions. An incorrect pfhFileHandleLockID on subsequent DosProtectxxx calls
|
|
results in an ERROR_ACCESS_DENIED return code.
|
|
|
|
The DosProtectxxx functions can be used with a NULL filehandle LockID, if the
|
|
subject filehandle was obtained from DosOpen.

BeginLIBPATH is searched before the system LIBPATH, and EndLIBPATH is searched
|
|
after both BeginLIBPATH and the system LIBPATH. These extended LIBPATHs can be
|
|
set either from the command line using the "SET" command, or by calling
|
|
DosSetExtLIBPATH. When DosSetExtLIBPATH is called, all modifications become
|
|
specific to that process. Initial settings can be set for all processes in the
|
|
system by setting the values in CONFIG.SYS using the "set" command.
|
|
|
|
Note: The extended LIBPATHs are not true environment variables, and do not
|
|
appear when querying the environment.
|
|
|
|
Every process inherits the settings of BeginLIBPATH and EndLIBPATH from the
|
|
process that starts it. If the extended library paths are initialized in
|
|
CONFIG.SYS, those extended library paths become the initial settings for new
|
|
processes. If a process changes BeginLIBPATH or EndLIBPATH and starts a new
|
|
process, the new child process inherits the changed contents. Child processes
|
|
that inherit their parent's extended LIBPATHs maintain their own copy.
|
|
Modifications made by the parent after the child has been created have no
|
|
effect on the children.
|
|
|
|
This function permits the use of two symbols within the path string:
|
|
%BeginLIBPATH% and %EndLIBPATH%. These symbols are replaced with the current
|
|
string settings for the extended library paths.
|
|
|
|
The LIBPATHs strings are only searched when the specified DLL is not currently
|
|
loaded. The only way to guarantee that the DLL being used is the correct
|
|
version is to set the fully-qualified path in DosLoadModule. When a request is
|
|
made to load a module and a path is not specified, the system searches the
|
|
paths in the LIBPATH string and uses the first instance of the specified DLL it
|
|
finds. If the new paths are added to the search strings, the system does not
|
|
check those directories to see if a different version exists. Consequently, if
|
|
two processes started from different directories use the same DLL, but
|
|
different versions of that DLL exist in both directories, the version of the
|
|
DLL loaded by the first process is the one used by both processes. The only way
|
|
to prevent this from occurring is to specify the path to the DLL when
|
|
DosLoadModule is called.
|
|
|
|
Consequently, if one process sets its BeginLIBPATH to C:\PROCESS1\DLL and loads
|
|
the DLL MYAPP.DLL from that directory, and then a second process sets its
|
|
BeginLIBPATH to C:\PROCESS2\DLL and there is for a different version of
|
|
MYAPP.DLL in C:\PROCESS2\DLL, the second process will link to the DLL from
|
|
C:\PROCESS1\DLL since it was already loaded.
|
|
|
|
Both BeginLIBPATH and EndLIBPATH can be set from the command line using the SET
|
|
command.

DosDumpProcess initiates a process dump from a specified process. This may be used as part of an error handling routine to gather information about an error that may be analyzed later using the OS/2 System Dump Formatter. Configuration of Process Dump may be done using the PDUMPSYS, PDUMPUSR, and PROCDUMP commands.
|
|
|
|
Parameters:
|
|
Flag = Function to be performed (one of DDP_* constants).
|
|
DDP_DISABLEPROCDUMP (0) - disable process dumps
|
|
DDP_ENABLEPROCDUMP (1) - enable process dumps
|
|
DDP_PERFORMPROCDUMP (2) - perform process dump (if the user enabled it using
|
|
the PROCDUMP command; ERROR_INVALID_PARAMETER is
|
|
returned otherwise)
|
|
Drive = The ASCII character for the drive on which process dump files are
|
|
to be created, or 0 to use the drive originally specified by the user
|
|
using the PROCDUMP command. This is required only with the
|
|
DDP_ENABLEPROCDUMP (PROCDUMP command allows customizing fully the drive
|
|
and path).
|
|
PID = The process to be dumped. 0 specifies the current process; otherwise
|
|
a valid process ID must be specified. This parameter is actioned only
|
|
with DDP_PERFORMPROCDUMP.
|
|
|
|
Possible return Codes.
|
|
0 NO_ERROR
|
|
87 ERROR_INVALID PARAMETER
|
|
|
|
Remarks:
|
|
Use the PDUMPUSR command to specify what information will be dumped.
|
|
|
|
Use the PROCDUMP command to customize options per process and in particular
|
|
to specify whether child or parent process will be dumped.
|
|
|
|
For maximum flexibility the use of DosDumpProcess should be limited
|
|
to the DDP_PERFORMPROCDUMP function. This allows you to specify whether
|
|
Process Dump should be enabled through the use of the PROCDUMP command.
|
|
You may customize Process Dump completely through use of the PDUMPUSR,
|
|
PDUMPSYS, AND PROCDUMP commands. For further information, see PROCDUMP.DOC
|
|
in the OS2\SYSTEM\RAS directory. DDP_ENABLEPROCDUMP and DDP_DISABLEPROCDUMP
|

are provided for backwards compatibility only.

Suppress application trap popups and log them to the file POPUPLOG.OS2.
|
|
|
|
Parameters:
|
|
Flag = Flag indicating whether pop-up suppression should be enabled
|
|
or disabled (one of SPU_* constants - 0 or 1).
|
|
Drive = The drive letter for the log file (used only when pop-up suppression is
|
|
enabled).
|
|
|
|
Remarks:
|
|
When pop-ups are suppressed through DosSuppressPopUps, the system does not
|
|
display trap screens on the user's terminal. The user will not be required
|
|
to respond to the abort, retry, continue message. Instead, the system displays
|
|
message SYS3571 and logs the name of the process to the POPUPLOG.OS2 log file
|
|
in the root directory of the specified drive. The system will also log
|
|
the message inserts in the log file.
|
|
|
|
If the log file does not exist, the system will create it. If the log file
|
|
exists, the system appends to it. If the system cannot open the file (for
|
|
example, because the drive does not exist), the system will not log the pop-up
|
|
information.
|
|
|
|
When pop-up suppression is enabled, the system overrides any settings
|
|
established by DosError on a per-process basis.
|
|
|
|
This API overrides the potential initial setting (e.g. 'SUPPRESSPOPUPS=c')
|
|
in CONFIG.SYS.
|
|
|
|
The drive letter for the log file may also be specified on the
|
|
DosSuppressPopUps API.
|
|
|
|
If an invalid flag (a flag other than SPU_ENABLESUPPRESSION
|
|
or SPU_DISABLESUPPRESSION) or an invalid drive (a drive other than an upper- or
|
|
lowercase letter) is specified on DosSuppressPopUps, the system returns error
|
|
code ERROR_INVALID_PARAMETER. Otherwise, the system returns NO_ERROR.
