From 7a31ef49c345dfb39de7cd6d43eeb29c34129495 Mon Sep 17 00:00:00 2001 From: rpj <rpj> Date: Wed, 7 Feb 2001 08:45:46 +0000 Subject: Updates and minor corrections and changes. --- README | 114 ----------------------------------------------------------------- 1 file changed, 114 deletions(-) (limited to 'README') diff --git a/README b/README index 0ca6271..250ada2 100644 --- a/README +++ b/README @@ -94,120 +94,6 @@ Otherwise neither pthreads cancelation nor pthread_exit() will work reliably. -Non-portable functions included in the library ----------------------------------------------- - -void -pthread_mutexattr_setforcecs_np(pthread_mutexattr_t *attr, - int forcecs); - - Allows an application to force the library to use - critical sections rather than win32 mutexes as - the basis for any mutex that uses "attr". - Critical sections are significantly faster than - mutexes. - - Values for "forcecs" are: - PTHREAD_MUTEX_AUTO_CS_NP - - allow the library to decide based on - availability of tryEnterCriticalSection(). - The library determines this at runtime - and will use critical sections whenever - tryEnterCriticalSection() is available. - PTHREAD_MUTEX_FORCE_CS_NP - - force use of critical sections even if - tryEnterCriticalSection() isn't provided - by the system, but you'd better not try - to use pthread_mutex_trylock() on any - mutex that uses "attr" if you want your - application to work on all versions of - Windows. - -HANDLE -pthread_getw32threadhandle_np(pthread_t thread); - - Returns the win32 thread handle that the POSIX - thread "thread" is running as. - - Applications can use the win32 handle to set - win32 specific attributes of the thread. - -int -pthread_delay_np (const struct timespec *interval); - - This routine causes a thread to delay execution for a specific period of time. - This period ends at the current time plus the specified interval. The routine - will not return before the end of the period is reached, but may return an - arbitrary amount of time after the period has gone by. This can be due to - system load, thread priorities, and system timer granularity. - - Specifying an interval of zero (0) seconds and zero (0) nanoseconds is - allowed and can be used to force the thread to give up the processor or to - deliver a pending cancelation request. - - This routine is a cancelation point. - - The timespec structure contains the following two fields: - - tv_sec is an integer number of seconds. - tv_nsec is an integer number of nanoseconds. - - Return Values - - If an error condition occurs, this routine returns an integer value - indicating the type of error. Possible return values are as follows: - - 0 Successful completion. - [EINVAL] The value specified by interval is invalid. - - -BOOL -pthread_win32_process_attach_np (void); - -BOOL -pthread_win32_process_detach_np (void); - -BOOL -pthread_win32_thread_attach_np (void); - -BOOL -pthread_win32_thread_detach_np (void); - - These functions contain the code normally run via dllMain - when the library is used as a dll but which need to be - called explicitly by an application when the library - is statically linked. - - You will need to call pthread_win32_process_attach_np() before - you can call any pthread routines when statically linking. - You should call pthread_win32_process_detach_np() before - exiting your application to clean up. - - pthread_win32_thread_attach_np() is currently a no-op, but - pthread_win32_thread_detach_np() is needed to clean up - after Win32 threads that have called pthreads routines - have exited. - - These functions invariably return TRUE except for - pthread_win32_process_attach_np() which will return FALSE - if pthreads-win32 initialisation fails. - - -int -pthreadCancelableWait (HANDLE waitHandle); - -int -pthreadCancelableTimedWait (HANDLE waitHandle, DWORD timeout); - - These two functions provide hooks into the pthread_cancel - mechanism that will allow you to wait on a Windows handle - and make it a cancellation point. Both functions block - until either the given w32 handle is signaled, or - pthread_cancel has been called. It is implemented using - WaitForMultipleObjects on 'waitHandle' and a manually - reset w32 event used to implement pthread_cancel. - - Building under VC++ using either C++ EH or Structured EH -------------------------------------------------------- -- cgit v1.2.3
