* 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.
