Does uClinux support shared memory (shmget)? I tried running a program with it but it doesnt seem to allocate the memory.

Starting from 2.6.5 or earlier, the official Linux kernel puts sys v IPC dependent on MMU. So you don't get any of IPC methods on uClinux.

Thanks for the reply Wentao. 

 

Well I was going through the uClinux email list archives and thought the versions>2.4 supported some Sys V IPC but I guess it doesn't. So I guess I'll try r/w from a file on a mounted fs.
