NAME         top

       pthread_mutexattr_init, pthread_mutexattr_destroy - initialize
       and destroy a mutex attributes object

SYNOPSIS         top

       #include <pthread.h>

       int pthread_mutexattr_init(pthread_mutexattr_t *attr);
       int pthread_mutexattr_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.
