posix shared memory regions

caverdave · 07-08-2009, 10:52 AM

Hi,

Does anybody know of how I can find a "directory listing" of shared memory regions (and hopefully their sizes), either in the /proc filesystem or something under /dev ? I thought I'd seen something before, but I can't find it now.

Thanks!

Apparently ipcs -m should do it, but read the full story here: http://www.webmasterworld.com/linux/3476321.htm

Unfortunately, ipcs only works for SYS V IPC, not POSIX. Oh well. From further searching, it seems there isn't a mechanism to see POSIX shared mem regions, just msg queues. I guess I'll have to go read Linux kernel source.

Thank you for your reply.
