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

NAME         top

       pthread_mutexattr_init,  pthread_mutexattr_destroy  -  initialize and
       destroy a mutex attributes object

SYNOPSIS         top

       #include <pthread.h>

       int pthread_mutex_init(pthread_mutexattr_t *attr);
       int pthread_mutex_destroy(pthread_mutexattr_t *attr);

       Compile and link with -pthread.

DESCRIPTION         top

       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.

RETURN VALUE         top

       On success, these functions return 0.  On error, they return a
       positive error number.

CONFORMING TO         top

       POSIX.1-2001, POSIX.1-2008.

NOTES         top

       Subsequent changes to a mutex attributes object do not affect mutex
       that have already been initialized using that object.
