IPC Shared Memory support in kernel?
 

How can I find out whether my kernel (2.4.8-26mdk) already supports shared memory, which I understand is a part of IPC or interprocess communications?
If it doesn't, how can I enable this support?

Shared Memory is supported by default, I think. In other words, I don't think shared memory is a compile option.

Shared Memory is IPC. try 'man shmget' on the command line. or 'man ipc' for more information.

or search google's linux section http://www.google.com/linux for 'shmget' system call
