64 Mutex attributes are used to specify parameters to
65 .Fn pthread_mutex_init .
66 One attribute object can be used in multiple calls to
67 .Fn pthread_mutex_init ,
68 with or without modifications between calls.
71 .Fn pthread_mutexattr_init
74 with all the default mutex attributes.
77 .Fn pthread_mutexattr_destroy
82 .Fn pthread_mutexattr_set*
83 functions set the attribute that corresponds to each function name.
86 .Fn pthread_mutexattr_get*
87 functions copy the value of the attribute that corresponds to each function name
88 to the location pointed to by the second function parameter.
90 If successful, these functions return 0.
91 Otherwise, an error number is returned to indicate the error.
