returns a copy of the file permission bits
as altered by the values pointed to by
While only the mode bits are altered, other parts of the file mode
takes an absolute (octal) or symbolic value, as described in
and returns a pointer to mode values to be supplied to
Because some of the symbolic values are relative to the file
If this occurs, the file creation mask will be restored before
If the calling program changes the value of its file creation mask
is to modify future file modes correctly.
