+ * Function: pthread_sigmask
+ *
+ * Description:
+ *   This function is a simple wrapper around sigprocmask().
+ *   See the sigprocmask() function description for further
+ *   information.
+ *
+ * Parameters:
+ *   how - How the signal mast will be changed:
+ *         SIG_BLOCK   - The resulting set is the union of
+ *                       the current set and the signal set
+ *                       pointed to by 'set'.
+ *         SIG_UNBLOCK - The resulting set is the intersection
+ *                       of the current set and the complement
+ *                       of the signal set pointed to by 'set'.
+ *         SIG_SETMASK - The resulting set is the signal set
+ *                       pointed to by 'set'.
+ *   set - Location of the new signal mask
+ *   oset - Location to store the old signal mask
+ *
+ * Return Value:
+ *   0 (OK) or EINVAL if how is invalid.
+ *
+ * Assumptions:
