/**********************************************************
*
* TEST IDENTIFIER : iopl01
*
* EXECUTED BY : superuser
*
* TEST TITLE : Basic test for iopl(2)
*
* TEST CASE TOTAL : 4
*
* AUTHOR : Subhab Biswas <sub...@wi...>
*
* SIGNALS
* Uses SIGUSR1 to pause before test if option set.
* (See the parse_opts(3) man page).
*
* DESCRIPTION
* This is a Phase I test for the iopl(2) system call.
* It is intended to provide a limited exposure of the system call.
*
* Setup:
* Setup signal handling.
* Test caller is superuser
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* Execute system call
* Check return code, if system call failed (return=-1)
* Issue FAIL message with errno.
* Otherwise, Issue PASS message.
*
* Cleanup:
* Print errno log and/or timing stats if options given
*
* USAGE: <for command-line>
* iopl01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-p]
* where, -c n : Run n copies concurrently.
* -e : Turn on errno logging.
* -h : Show help screen
* -f : Turn off functional testing
* -i n : Execute test n times.
* -I x : Execute test for x seconds.
* -p : Pause for SIGUSR1 before starting
* -P x : Pause for x seconds between iterations.
* -t : Turn on syscall timing.
*

* DESCRIPTION
* Verify that

* Set expected errnos for logging
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* Execute system call
* Check return code and error number, if matching,
* Issue PASS message
* Otherwise,
* Issue FAIL message
* Perform testcase specific cleanup (if needed)
