PTHREAD_MUTEXATTR_INIT(3) Linux Programmer's ManualPTHREAD_MUTEXATTR_INIT(3)
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.
