- UMASK(2) Minix Programmer's Manual UMASK(2)
- 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.
- SEE ALSO
- chmod(2), mknod(2), open(2).
