NAME

6       getumask - get file creation mask
7

SYNOPSIS

9       #define _GNU_SOURCE             /* See feature_test_macros(7) */
10       #include <sys/types.h>
11       #include <sys/stat.h>
12
13       mode_t getumask(void);
14

DESCRIPTION

16       This function returns the current file creation mask.  It is equivalent
17       to
18
19           mode_t getumask(void)
20           {
21               mode_t mask = umask( 0 );
22               umask(mask);
23               return mask;
24           }
25
26       except that it is documented to be thread-safe (that is, shares a  lock
27       with the umask(2) library call).
28

CONFORMING TO

30       This is a vaporware GNU extension.
31

NOTES

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