NAME
     Pumask - set file and directory creation mask

SYNOPSIS
     WORD Pumask( WORD mode );

DESCRIPTION
     Pumask changes the file and directory creation mask  of  the
     current process to the unsigned 16 bit quantity specified in
     mode.  The old value of the creation mask is returned. Child
     processes inherit the new value for the mask.

     When a new file is created with Fcreate or a  new  directory
     created  with  Dcreate  the  initial access permissions (see
     Fchmod for a description of these)  for  the  newly  created
     file  or  directory are normally set so that all permissions
     are granted (except that execute permission is not  normally
     granted  for  files). The creation mask set by Pumask deter-
     mines which permissions are not to be  granted  by  default.
     Thus,  files created after a Pumask(S_IWOTH|S_IWGRP|S_IXOTH)
     call will be readable by anyone, but writable  only  by  the
     owner;  moreover,  directories created after this call would
     be searchable by the owner and members of  the  same  group,
     but not by anyone else.

BUGS
     Pumask doesn't affect explicit Fchmod calls, as  some  might
     expect.
