NAME
     mtx_init – initialize a mutex

SYNOPSIS
     library “threads”
     #include <threads.h>

     int
     mtx_init(mtx_t *mtx, int type);

DESCRIPTION
     The function mtx_init() initializes a mutex mtx of the given type.

     The type argument can be either of

     mtx_plain
	     a simple mutex, can be shared across child processes.

     mtx_timed
	     a simple mutex, can be shared across child processes, allows
	     timed locking.

     mtx_plain | mtx_recursive
	     a simple mutex, can be shared across child processes, the same
	     thread can acquire the lock multiple times recursively. It must
	     be unlocked by an equal amount of times by the thread.

     mtx_timed | mtx_recursive
	     a simple mutex, can be shared across child processes, allows
	     timed locking, the same thread can acquire the lock multiple
	     times recursively. It must be unlocked by an equal amount of
	     times by the thread.

RETURN VALUES
     Upon success mtx_init() returns thrd_success, if there is insufficient
     memory it will return thrd_nomem in case of any other error thrd_error
     will be returned.
