* NAME
|
|
* msgget01.c
|
|
*
|
|
* DESCRIPTION
|
|
* msgget01 - create a message queue, write a message to it and
|
|
* read it back.
|
|
*
|
|
* ALGORITHM
|
|
* loop if that option was specified
|
|
* create a message queue
|
|
* check the return code
|
|
* if failure, issue a FAIL message.
|
|
* otherwise,
|
|
* if doing functionality testing by writting a message to the queue,
|
|
* reading it back and comparing the two.
|
|
* if the messages are the same,
|
|
* issue a PASS message
|
|
* otherwise
|
|
* issue a FAIL message
|
|
* call cleanup
|
|
*
|
|
* USAGE: <for command-line>
|
|
* msgget01 [-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.
