/*
|
||
* Test Name: mknod09
|
||
*
|
||
* Test Description:
|
||
* Verify that, mknod() fails with -1 and sets errno to EINVAL if the mode is
|
||
* different than a normal file, device special file or FIFO.
|
||
*
|
||
* Expected Result:
|
||
* mknod() should fail with return value -1 and sets expected errno.
|
||
*
|
||
* Algorithm:
|
||
* Setup:
|
||
* Setup signal handling.
|
||
* Check id is super/root
|
||
* Pause for SIGUSR1 if option specified.
|
||
* Create temporary directory.
|
||
*
|
||
* Test:
|
||
* Loop if the proper options are given.
|
||
* Execute system call
|
||
* Check return code, if system call failed (return=-1)
|
||
* if errno set == expected errno
|
||
* Issue sys call fails with expected return value and errno.
|
||
* Otherwise,
|
||
* Issue sys call fails with unexpected errno.
|
||
* Otherwise,
|
||
* Issue sys call returns unexpected value.
|
||
*
|
||
* Cleanup:
|
||
* Print errno log and/or timing stats if options given
|
||
* Delete the temporary directory created.
|
||
*
|
||
* Usage: <for command-line>
|
||
* mknod09 [-c n] [-e] [-f] [-i n] [-I x] [-P x] [-t]
|
||
* where, -c n : Run n copies concurrently.
|
||
* -e : Turn on errno logging.
|
||
* -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.
