umask

# $EPIC: umask.txt,v 1.2 2006/08/20 17:37:08 sthalik Exp $

Synopsis:

$umask(<mask>)

Technical:

This function sets the default file umask used when creating and writing files with EPIC's builtin file functions. The umask sets the permission bits to block when writing. Essentially, the resultant permission bits would be the default minus the umask.

Practical:

This function is used to set the default file permissions. The $chmod() function is affected by it.

Returns:

previous umask, or nothing if no new umask is given

Examples:

$umask(77)                 sets default permissions to 700
$umask(2)                  sets default permissions to 775
$umask()                   error, no mask, returns nothing
