 | |
|  * 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.
