/*
* Test Name: access03
*
* Test Description:
* Verify that,
* 1. access() fails with -1 return value and sets errno to EACCES
* if the permission bits of the file mode do not permit the
* requested (Read/Write/Execute) access.
* 2. access() fails with -1 return value and sets errno to EINVAL
* if the specified access mode argument is invalid.
* 3. access() fails with -1 return value and sets errno to EFAULT
* if the pathname points outside allocate address space for the
* process.
* 4. access() fails with -1 return value and sets errno to ENOENT
* if the specified file doesn't exist (or pathname is NULL).
* 5. access() fails with -1 return value and sets errno to ENAMETOOLONG
* if the pathname size is > PATH_MAX characters.
*
* Expected Result:
* access() 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>
* access03 [-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 run by 'non-super-user' only.
