in this unix book that i have, it says:
the statement:
filedes = open(pathname, O_CREAT, mode);
is actually
filedes = open(pathname, O_CREAT, (~mask)&mode); /* ~ is the negation symbol */
like it's doing some type of masking.
for example,

newgrp
NEWGRP(1) BSD General Commands Manual NEWGRP(1)NAME
newgrp -- change to a new group
SYNOPSIS
newgrp [-l] [group]
DESCRIPTION
The newgrp utility creates a new shell execution environment with modified real and effective group IDs.
The options are as follows:
-l Simulate a full login. The environment and umask are set to what would be expected if the user actually logged in again.
If the group operand is present, a new shell is started with the specified effective and real group IDs. The user will be prompted for a
password if they are not a member of the specified group.
Otherwise, the real, effective and supplementary group IDs are restored to those from the current user's password database entry.
EXIT STATUS
The newgrp utility attempts to start the shell regardless of whether group IDs were successfully changed.
If an error occurs and the shell cannot be started, newgrp exits >0. Otherwise, the exit status of newgrp is the exit status of the shell.
SEE ALSO csh(1), groups(1), login(1), sh(1), su(1), umask(1), group(5), passwd(5), environ(7)STANDARDS
The newgrp utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A newgrp utility appeared in Version 6 AT&T UNIX.
BUGS
For security reasons, the newgrp utility is normally installed without the setuid bit. To enable it, run the following command:
chmod u+s /usr/bin/newgrp
Group passwords are inherently insecure as there is no way to stop users obtaining the password hash from the group database. Their use is
discouraged. Instead, users should simply be added to the necessary groups.
