/*
* Test Name: ftruncate03
*
* Test Description:
* Verify that,
* 1) ftruncate(2) returns -1 and sets errno to EINVAL if the specified
* truncate length is less than 0.
* 2) ftruncate(2) returns -1 and sets errno to EBADF if the file descriptor
* of the specified file is not valid.
*
* Expected Result:
* ftruncate() should fail with return value -1 and set expected errno.
*
* Algorithm:
* Setup:
* Setup signal handling.
* Create temporary directory.
* 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)
* 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(s)/file(s) created.
*
* Usage: <for command-line>
* ftruncate03 [-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.
*
* HISTORY
* 07/2001 Ported by Wayne Boyer
*
* RESTRICTIONS:
* This test should be executed by 'non-super-user' only.
