Thanks for your reply, but I afraid you did not get my point. I am talking about shared memory that is used for Interprocess communication. We can access the shared memory created by one C program in other C program and same is the case with php. I am trying to communicate with a C program from php using shared memory, but I did not get it working till now.
To be more specific, I want to know 1. Are calls to function ftok() return the same key in both php and C 2. Is the function shmop_open() return the same shared memory as shmget() system call, when we pass the same key to both the functions. Thanks in advance ramana.
