/*
* NAME
* exit02.c
*
* DESCRIPTION
* Check that exit flushes output file buffers and closes files upon
* exitting
*
* ALGORITHM
* Fork a process that creates a file and writes a few bytes, and
* calls exit WITHOUT calling close(). The parent then reads the
* file. If everything that was written is present in the file, then
* the test passes.
*
* USAGE
* exit02
*
* HISTORY
* 07/2001 Ported by Wayne Boyer
*
* RESTRICTIONS
* None
