|
NAME
|
|
umask - set file creation mode mask
|
|
|
|
SYNOPSIS
|
|
#include <sys/types.h>
|
|
#include <sys/stat.h>
|
|
|
|
mode_t umask(mode_t mask)
|
|
|
|
DESCRIPTION
|
|
Umask sets the process's file mode creation mask to mask and returns the
|
|
previous value of the mask. The low-order 9 bits of mask are used
|
|
whenever a file is created, clearing corresponding bits in the file mode
|
|
(see chmod(2)). This clearing allows each user to restrict the default
|
|
access to his files.
|
|
|
|
The value is initially 022 (write access for owner only). The mask is
|
|
inherited by child processes.
|
|
|
|
RETURN VALUE
|
|
The previous value of the file mode mask is returned by the call.
