Does Linux (specifically RedHat 6.2) support Posix message queues, or only System V queues, and where can I find detailed information about what system calls are and are not supported in a given kernel (other than checking for the various header files)? I'm just beginning to program under Unix, and I'm working from several Unix programming books that stress portability using the Posix.1 spec and/or the Unix98 spec. One book specifically stated that Solaris and HPUX were the only flavors to have passed all the authors tests of Posix IPC compliance. I have read several Linux-based programming tutorials, and looked through the linuxdoc.org site, but I didn't see detailed information on the available system calls.
