+.Sh DESCRIPTION
+Mutex attributes are used to specify parameters to
+.Fn pthread_mutex_init .
+One attribute object can be used in multiple calls to
+.Fn pthread_mutex_init ,
+with or without modifications between calls.
+
+The
+.Fn pthread_mutexattr_init
+function initializes
+.Fa attr
+with all the default mutex attributes.
+
+The
+.Fn pthread_mutexattr_destroy
+function destroys
+.Fa attr .
+
+The
+.Fn pthread_mutexattr_set*
+functions set the attribute that corresponds to each function name.
+
+The
+.Fn pthread_mutexattr_get*
+functions copy the value of the attribute that corresponds to each function name
+to the location pointed to by the second function parameter.
+
+.Sh RETURN VALUES
+If successful, these functions return 0.
+Otherwise, an error number is returned to indicacte the error.
