pthread_mutexattr_init, pthread_mutexattr_destroy - initialize and destroy a
mutex attributes object
#include <pthread.h>
int pthread_mutexattr_init(pthread_mutexattr_t *attr);
int pthread_mutexattr_destroy(pthread_mutexattr_t *attr);
Compile and link with
-pthread.
The
pthread_mutexattr_init() function initializes the mutex attributes
object pointed to by
attr with default values for all attributes
defined by the implementation.
The results of initializing an already initialized mutex attributes object are
undefined.
The
pthread_mutexattr_destroy() function destroys a mutex attribute
object (making it uninitialized). Once a mutex attributes object has been
destroyed, it can be reinitialized with
pthread_mutexattr_init().
The results of destroying an uninitialized mutex attributes object are
undefined.
On success, these functions return 0. On error, they return a positive error
number.
POSIX.1-2001, POSIX.1-2008.
Subsequent changes to a mutex attributes object do not affect mutex that have
already been initialized using that object.
