file locking in GNU pascal for Linux

I have a pascal program that has to be launched by a PHP script on server in Linux environment. This program reads/writes a lot of files. How could I lock a read or written file to properly manage multiple users access ? In C language this is a 'flock' function, but I could not find a similar function in Pascal. I use GNU pascal compiler gpc for linux.
Thank you in advance for a response.

FreePascal has an flock function in the 'linux' unit.

I have also found that it generates much smaller and faster applications than GPC.

The rest of your code should be be portable with a few minor 'tweaks'.
