getumask - get file creation mask

#include <sys/types.h>
#include <sys/stat.h>

mode_t getumask(void);

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() library call).

This function is documented but not implemented yet in glibc 2.2.5.

This is a vapourware GNU extension.
