[MacPerl] file-locking algorithm

[pr1@club-internet.fr (Philippe de Rochambeau)]

I am currently designing a Perl program that lets people search through a
text-file database using an HTML form. Can anyone suggest a simple
file-locking algorithm to prevent several users on the Web from opening the
file at the same time?

Question: does the Perl command "open" die whenever a file is being used by
another acgi on the server machine?

Although I am designing and testing this Perl program on a Macintosh, I
plan to eventually put it on an Unix server. As a result, the file-locking
should also work on Unix, if possible.

Many thanks.
