NAME    [Toc]    [Back]

     lockspool - lock user's system mailbox

SYNOPSIS    [Toc]    [Back]

     lockspool [username]

DESCRIPTION    [Toc]    [Back]

     lockspool is useful for a  client  mail  program  to  attain
proper locking.
     lockspool  obtains  a username.lock for the calling user and
retains it until
 stdin is closed or a signal  like  SIGINT,  SIGTERM,  or
SIGHUP is received.
  Additionally, the superuser may specify the name of
a user in
     order to lock a different mailbox.

     If lockspool is able to create the lock file, ``1'' is written to stdout,
     otherwise  ``0''  is written and an error message is written
to stderr.
     lockspool will try up to 10 times to get the lock  (sleeping
for a short
     period in between tries).

     The  lockspool utility exits 0 on success, and 1 if an error
occurs.
