umask - set file creation mask
mode_t umask(mode_t mask);
umask sets the umask to mask & 0777.
The umask is used by open(2) to set initial file permissions on a
newly-created file. Specifically, permissions in the umask are turned
off from the mode argument to open(2) (so, for example, the common
umask default value of 022 results in new files being created with per-
missions 0666 & ~022 = 0644 = rw-r--r-- in the usual case where the
mode is specified as 0666).
This system call always succeeds and the previous value of the mask is
