NAME
       getumask - get file creation mask

SYNOPSIS
       #define _GNU_SOURCE	       /* See feature_test_macros(7) */
       #include <sys/types.h>
       #include <sys/stat.h>

       mode_t getumask(void);

DESCRIPTION
       This function returns the current file creation mask.  It is equivalent to

	   mode_t getumask(void)
	   {
	       mode_t mask = umask( 0 );
	       umask(mask);
	       return mask;
	   }

       except  that  it is documented to be thread-safe (that is, shares a lock with the umask(2)
       library call).

CONFORMING TO
       This is a vaporware GNU extension.

NOTES
       This function is documented but not implemented yet in glibc, as at version 2.9.
