Each port that allows the usage of dynamic libraries should call InitSystemDynLibs during initialization of the System unit.
The DynLibs unit has been adjusted to be a forwarder for the functions that now reside in the System unit (for backwards compatiblity just in case). Additionally the unit will register the DynLibsManager if it doesn't reside in the System unit anyway.
Currently only the Windows targets (Win32, Win64 and WinCE) implement the DynLibsManager inside the System unit. For other systems using the LoadLibrary, etc. functions will lead to a run error/exception.
If a port wants to implement its own DynLibsManager then it needs to define DISABLE_NO_DYNLIBS_MANAGER. TLibHandle, NilHandle and optionally TOrdinalEntry (it's set to SizeUInt otherwise) should be defined in sysdlh.inc which needs to be enabled using the define FPC_SYSTEM_HAS_SYSDLH (because there are targets which have FEATURE_DYNLIBS enabled, but don't support them... e.g. powerpc-wii -.-).
The DynLibsManager contains methods for loading a library based on a RawByteString and based on a UnicodeString. BOTH should be implemented, but internally one can forward to the other.
The loading by ordinal *can* be be implemented. If it is set to Nil then the implementation of GetProcAddress(lib,ordinal) will return Nil.
+ new functions SetDynLibsManager and GetDynLibsManager to set and retrieve the current DynLibsManager
* provide interface of DynLibs unit in unit System

- fixed all Amiga-like system units to not leak the last directory
lock while changing back to the original dir in System_exit;
(a bug found by Marcus Sackrow, thanks!)
* renamed AOS_origDir to ASYS_origDir
git-svn-id: trunk@28537 -
* It fixes regression of tw16283b after r27169.
* BeOS, Haiku: added fpc_cpucodeinit to compensate for removal of SysInitFPU, it also enables use of CPU features like SSE.
git-svn-id: trunk@27171 -
into rawbytestring because otherwise -gt can overwrite it
- removed hack from r25944 in morphos/sysutils.pp that worked around this
problem
git-svn-id: trunk@25952 -
o these routines are now generic wrappers in filutil.inc, and call
the platform-dependent internalfindfirst/next/close routines
o on unix, the fnmatch routine got proper support for UTF-8 matching
(e.g., it won't match a partial UTF-8 code point to a "?" wildcard)
o for NativeNT, a similar (untested) UTF-16 version has been added
+ test for the above
* rawbytestring/unicodestring versions of fileage
git-svn-id: branches/cpstrrtl@25302 -
+ codepage support for textrec/filerec and the above routines
* textrec/filerec now store the filename by default using widechar. It is
possible to switch back to ansichars using the FPC_ANSI_TEXTFILEREC define.
In that case, from now on the filename will always be stored in
DefaultFileSystemEncoding
* fixed potential buffer overflows and non-null-terminated file names in
textrec/filerec
+ dodirseparators(pwidechar), changed the dodirseparators(pchar/pwidechar)
parameters into var-parameters and gave those routines an extra parameter
that indicates whether the p(wide)char can be changed in place if
necessary or whether a copy must be made first (avoids us having to make
all strings always unique everywhere, because they might be changed on
some platforms via a pchar)
* do_open/do_erase/do_rename got extra boolean parameters indicating whether
the passed pchars point to data that can be freely changed (to pass on to
dodirseparators() if applicable)
* objects.pp: force assign(pchar) to be called, because
assign(array[0..255]) cannot choose between pchar and rawbytestring
versions (and removing the pchar version means that assign(pchar) will
be mapped to assign(shortstring) in {$h-})
* fixed up some routines in other units that depend on the format of
the textrec/filerec.name field
git-svn-id: branches/cpstrrtl@25137 -
so declarations can also depend on it and similar defines (not yet the
case)
+ added SYSUTILS_HAS_ANSISTR_ENVVAR_IMPL/SYSUTILS_HAS_UNICODESTR_ENVVAR_IMPL
to indicate whether the platform-dependent part of the unit provides
an ansistring/unicodestring interface to get environment variables
+ Windows version of getenvironmentvariable(unicodestring)
+ generic ansistring/unicodestring versions of GetEnvironmentVariable()
in case the platform doesn't provide them
* result of GetEnvironmentString() is ansistring/unicodestring depending
on the state of the FPC_RTL_UNICODE define
git-svn-id: branches/cpstrrtl@25116 -
CreateDir and RemoveDir, and implemented a generic one (based on the OS/2
version) in the shared sysutils code (so that the filesystem code page
support for the system unit routines can be reused)
* include both ansistring and unicodestring versions of the above routines,
and of ForceDirectories. Exception: GetCurrentDir, which cannot be
overloaded based on function result and whose return type currently
dependends on the FPC_UNICODE_RTL define
