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.)
