This paper is an introduction to programming on the X system. The emphasis is on how to write programs that interface to the operating system, either directly or through the standard I/O library. The topics discussed include
" \(bu"
handling command arguments
" \(bu"
rudimentary I/O; the standard input and output
" \(bu"
the standard I/O library; file system access
" \(bu"
low-level I/O: open, read, write, close, seek
" \(bu"
processes: exec, fork, pipes
" \(bu"
signals \(em interrupts, etc.
There is also an appendix which describes
the standard I/O library in detail.
