NAME

umask - set file creation mode mask

SYNOPSIS

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

int umask(int mask);

DESCRIPTION

umask sets the process's file 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 access permissions (see stat). This clearing restricts the default access to a file. The mask is inherited by child processes.

RETURN VALUES

umask returns the previous value of the file creation mask.
