Especially for the introduction of the Queue method the internal Synchronize handling was modified. Instead of handling only one event there is now a queue of events which is walked completely when CheckSynchronize is called. Each entry in the queue can carry a PRTLEvent which will be signaled when the contained method has been executed and thus Synchronize methods can still be blocking. Exceptions inside the queued methods are either handed back to the calling method for Synchronize events or raised directly (after leaving the queue in a valid state) to the caller of CheckSynchronize. The way platform specific adjustments can be made to TThread was changed. Instead of implementing the Constructor and Destructor directly one now implements the methods SysCreate and SysDestroy which are called from the Constructor and Destructor respectively. All RTLs were adjusted for this and should be controlled by the platform maintainers for correct compilation (Unix works). The new method NameThreadForDebugging has two overloaded variants: one with the thread name as AnsiString and one with the thread name as UnicodeString. By default the AnsiString variant calls the UnicodeString variant and the latter needs to be implemented. This can be changed by defining THREADNAME_IS_ANSISTRING for a platform. Then the UnicodeString variant calls the AnsiString one and the AnsiString one needs to be implemented. Also added was a global property CPUCount for the System unit. This property returns the number of virtual cores of the system. New methods and functions that should be implemented per platform are: System.GetCPUCount (default returns 1) Classes.TThread.GetSystemTimes (default zeros the struct) Classes.TThread.NameThreadForDebugging (default does nothing) More detailed information about the added methods will be available in the feature announcement mail. git-svn-id: trunk@23227 - |

This directory contains units that are part of the Object Pascal support
of the Free Pascal Compiler.
You can find here the following files:
objpas.pp : makes Free Pascal more Borland Delphi compatible, data types
are redefined
math.pp : Contains basic mathematical functions, as well as some financial
functions.
sysutils.pp : Contains the exception support of the Free Pascal Compiler.
sysutils/*h.inc : Contain parts of the sysutils unit, with function declarations.
sysutils/*.inc : Contain parts of the sysutils unit, with implementations of:
dati : Date & Time handling functions.
fina : FileName handling functions.
sysstr : miscellaneous string handling functions, and conversion
routines.
syspch : miscellaneous pchar handling functions.
