* Name: pthread_sigmask
*
* Description:
* This function is a simple wrapper around nxsig_procmask().
* See the nxsig_procmask() function description for further
* information.
*
* Input Parameters:
* how - How the signal mask 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
*
* Returned Value:
* On success, this function will return 0 (OK). It will return EINVAL if
* how is invalid.
*
