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 }

26 except that it is documented to be thread-safe (that is, shares a lock
27 with the umask(2) library call).
28
30 This is a vaporware GNU extension.
31
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.)
