CRA-1’s System calls
- Modeled after UNIX system calls (for a complete list on Solaris 2.5.1, try typing “man -s 2 intro” on xi.cs.fsu.edu)
 - Simplified subset of common system calls broken down into three areas:
- File and I/O System calls: open(), creat(), read(), write(), lseek(), close(), unlink(), and stat()
 - Process Management System calls: CreateProcess(), Exit(), Wait()
 - InterProcess Communication (IPC) System calls: CreateMessageQueue(), SendMessage(), ReceiveMessage(), DestroyMessageQueue()
