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