FreePascal has an flock function in the 'linux' unit.<br />
<br />
I have also found that it generates much smaller and faster applications than GPC.<br />
<br />
The rest of your code should be be portable with a few minor 'tweaks'.<br />

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.<br />
Thank you in advance for a response.

file locking in GNU pascal for Linux

Pascal is an influential imperative and procedural programming language, largely (but not exclusively) intended to teach students structured programming and data structuring. Pasca was implemented on a wide range of architectures, from early PCs to mainframes. Pascal derivatives include OOP-based Object Pascal (used in Delphi and Lazarus/Free Pascal). Pascal is a purely procedural language and includes control statements with reserved words, but has many data structuring facilities and other abstractions like type definitions, records, pointers, enumerations, and sets.
