Non-portable functions included in pthreads-win32
-------------------------------------------------
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_mutexattr_setkind_np(pthread_mutexattr_t * attr, int kind)
int
pthread_mutexattr_getkind_np(pthread_mutexattr_t * attr, int *kind)
These two routines are included for Linux compatibility
and are direct equivalents to the standard routines
pthread_mutexattr_settype
pthread_mutexattr_gettype
pthread_mutexattr_setkind_np accepts the following
mutex kinds:
PTHREAD_MUTEX_FAST_NP
PTHREAD_MUTEX_ERRORCHECK_NP
PTHREAD_MUTEX_RECURSIVE_NP
These are really just equivalent to (respectively):
PTHREAD_MUTEX_NORMAL
PTHREAD_MUTEX_ERRORCHECK
PTHREAD_MUTEX_RECURSIVE
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.
