GETUMASK(3) Linux Programmer's Manual GETUMASK(3)

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 in the glibc manual, but, as at glibc ver-
     sion 2.24, it is not implemented on Linux.  (See umask(2) for a thread-
     safe method of discovering a process's umask.)

SEE ALSO
