Well, message queues and semaphore functions are optional extensions to Posix1.b. Both of which require kernel support, as they have system wide namespace. No one has ever written the kernel support, so glibc has never added the userspace functions for them. I have the kernel space code partically implimented somewhere, but every time I have posted asking if someone was interested in actually using these features of Posix.1b I get no response. If you are interested in actually writing this code ir have an application you really want it for, email me. Maybe I'll spend a weekend and get them working. Most people just use SYSV message queues and semaphore right now, which are supported but glibc.
