|
* dup204.c
|
|
*
|
|
* DESCRIPTION
|
|
* Testcase to check the basic functionality of dup2(2).
|
|
*
|
|
* ALGORITHM
|
|
* attempt to call dup2() on read/write ends of a pipe
|
|
*
|
|
* USAGE: <for command-line>
|
|
* dup204 [-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.
|
|
*
|
|
* RESTRICTION
|
