## Name

pthread_win32_process_attach_np, pthread_win32_process_detach_np, pthread_win32_thread_attach_np, pthread_win32_thread_detach_np – exposed versions of the pthreads-w32 DLL dllMain() switch functionality for use when statically linking the library.

## Synopsis

#include <pthread.h>

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);

## Description

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 the implicit pthread handle that is allocated to a Win32 thread if it calls certain pthreads routines. Call this routine when the Win32 thread exits.

These functions invariably return TRUE except for pthread_win32_process_attach_np which will return FALSE if pthreads-w32 initialisation fails.

## Cancellation

None.

## Return Value

These routines return TRUE (non-zero) on success, or FALSE (0) if they fail.

## Errors

None.
