I came across the following program to implement a shared memory IPC between a client and a server.
The following line is used to generate a unique sysv key (as mentioned here):
ShmKEY = ftok(".", 'x');
What does a pathname "." mean in this case? I am completely new to linux and a clear-cut answer will be much appreciated.
Pathname "." means the current directory. You can find more details of function here Or executing command man ftok in your Linux machine.
