Non-portable functions included in the library
----------------------------------------------

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.


void
pthread_mutexattr_setforcecs_np(pthread_mutexattr_t *attr,
				int forcecs);

        This function is no longer required as pthreads-win32
        mutexes are now based entirely on Win32 critical
        sections. Retained for backward compatibility.

	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.
