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

NAME         top

       getumask - get file creation mask

SYNOPSIS         top

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

       mode_t getumask(void);

DESCRIPTION         top

       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         top

       This is a vaporware GNU extension.

NOTES         top

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