+        The routine sets the default type to be given to all
+        POSIX mutexes initialised after the function
+        is called. Any of the following type values
+        can be made the default type:
+
+          PTHREAD_MUTEX_NORMAL
+          PTHREAD_MUTEX_ERRORCHECK
+          PTHREAD_MUTEX_RECURSIVE
+          PTHREAD_MUTEX_DEFAULT
+
+        Any mutex initialised with type PTHREAD_MUTEX_DEFAULT
+        will be set to the mapped type instead. Previously
+        initialised mutexes are not changed.
+
+        When set to PTHREAD_MUTEX_DEFAULT (the initial
+        value), mutexes will behave as for the
+        PTHREAD_MUTEX_RECURSIVE type.
+
+        If 'oldtype' is a non-NULL pointer, the previous type is
+        returned through it.
+        To get the previous type without setting a new type,
+        use -1 as the 'newtype' value.
