When a process fork(), the child share the same file descriptors as his father. Thus, they share the same stdin. Quick and dirty exemple below (sorry for the ugly gets() call) :

It is a spell checking program which prints each misspelled word on a line of its own. OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options are included below. For a complete description, see the Info files. -I, --ispell-version Print Ispell's version. -V, --version Print the version number. -b, --british Use the British dictionary. -d, --dictionary=FILE Use FILE to look up words. -h, --help Print a summary of the options. -i, --ispell=PROGRAM Calls PROGRAM as Ispell. -D, --ispell-dictionary=DICTIONARY Use the named DICTIONARY to look up words. -l, --all-chains Ignored; for compatibility. -n, --number Print line numbers before lines. -o, --print-file-name Print file names before lines. -s, --stop-list=FILE Ignored; for compatibility. -v, --verbose Print words not literally found. -x, --print-stems Ignored; for compatibility.
