I believe the reason for your problem is simple: you cannot use most of the "normal" C library or system calls within RTLinux, because you are within the kernel, and not in user space. This is a topic that comes up periodically, and there are ways to bring in functions you need, but only some of them. If you go to the linux source tree and type "make psdocs" or "make pdfdocs" in the Documentation directory, you should end up with a bunch of docbooks, including kernel-api.pdf. This will give you (very short) manpages for the functions available within the kernel. More generally, you need to do only the absolute minimum of work inside the kernel, and let your user-space code do as much work as possible. You transfer data to user-space via fifos or shared memory.
