1. Functions LOCK & UNLOCK using NAMED PIPES and CREATE & UNLINK
Hi everyone :)
Does anyone know how to write the function "lock" and also "unlock" in C using
the following:
1) named pipes
2) "create" and "unlink" system calls
3) message system calls
Please e-mail me a sample C code for each case. Thanks for your help :)
