* NAME
|
|
* shmdt02.c
|
|
*
|
|
* DESCRIPTION
|
|
* shmdt02 - check for EINVAL error
|
|
*
|
|
* ALGORITHM
|
|
* loop if that option was specified
|
|
* call shmdt() using an invalid shared memory address
|
|
* check the errno value
|
|
* issue a PASS message if we get EINVAL
|
|
* otherwise, the tests fails
|
|
* issue a FAIL message
|
|
* call cleanup
|
|
*
|
|
* USAGE: <for command-line>
|
|
* shmdt02 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on errno logging.
|
|
* -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.
