mtx_init(3c)

Standard C Library Functions                                      mtx_init(3C)



NAME
       mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, mtx_destroy
       - C11 mutex functions

SYNOPSIS
       #include <threads.h>


       int mtx_init(mtx_t *mtx, int type);


       int mtx_lock(mtx_t *mtx);


       int mtx_timedlock(mtx_t *restrict mtx,
                 const struct timespec *restrict ts);


       int mtx_trylock(mtx_t *mtx);


       int mtx_unlock(mtx_t *mtx);


       void mtx_destroy(mtx_t *mtx);

DESCRIPTION
       The    mtx_init(),    mtx_lock(),    mtx_timedlock(),    mtx_trylock(),
       mtx_unlock(),  and  mtx_destroy()  functions  are  part  of the threads
       interfaces as specified in the C11 standard. They are  simple  wrappers
       over the more general pthreads functions. See INCITS/ISO/IEC 9899:2011.

RETURN VALUES
       Upon  successful  completion,  each  of  the  mtx_init(),   mtx_lock(),
       mtx_timedlock(),   mtx_trylock(),  and  mtx_unlock()  functions  return
       thrd_success. If the requested resource is not  acquired  in  the  time
       specified by ts, the mtx_timedlock() function returns thrd_timedout. If
       the resource requested by mtx_trylock() is  already  in  use,  mtx_try‐
       lock() returns thrd_busy. If the request could not otherwise be honored
       by any of these functions, thrd_error is returned.


       No value is returned by the mtx_destroy() function.
