/*
* NAME
* close01.c
*
* DESCRIPTION
* Test that closing a regular file and a pipe works correctly
*
* ALGORITHM
* Creat a file, and dup() a fildes
* Open a pipe
* call close() using the TEST macro
* if the call fails
* issue a FAIL message and continue
* else if STD_FUNCTIONAL_TEST
* attempt to close the file/pipe again
* if there is an error
* issue a PASS message
* else
* issue a FAIL message
* else
* issue a PASS message
*
*
* USAGE: <for command-line>
* close01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
* where, -c n : Run n copies concurrently.
* -f : Turn off functionality Testing.
* -i n : Execute test n times.
* -I x : Execute test for x seconds.
* -P x : Pause for x seconds between iterations.
* -t : Turn on syscall timing.
*
* HISTORY
* 07/2001 Ported by Wayne Boyer
*
* RESTRICTIONS
* None
