file locking?

Can anyone point me to a place where I can read up on file locking for Linux?   I mean shared verses non-shared file access.

thanks

1. More mail file locking questions (lockf, NFS, /var/spool/mail/*.lock)

        Here's a problem I've run into:

        The problem I've seen relates to building mh-6.8 for SVR4
        (and correspondingly LOCKF). Now, it appears that while
        INC believes the mail file (NFS mounted) should be
        locked, it isn't (or it is lockf'ed and someone else
        [/bin/mail?] isn't honoring the lock; it says something
        like "New mail has arrived.."). It appears that /bin/mail
        (on 4.1.x and Solaris 2.x) uses lock files
        (/var/spool/mail/*.lock).  

        My question is, should mh ({l}emacs, popper,imap,...)
        use this style (and abandon lockf), or is there some
        other appropriate solution to this problem?

        Thanks,
