|
|
* Test Name : symlink03
|
|
*
|
|
* Test Description :
|
|
* Verify that,
|
|
* 1) symlink(2) returns -1 and sets errno to EACCES if search/write
|
|
* permission is denied in the directory where the symbolic link is
|
|
* being created.
|
|
* 2) symlink(2) returns -1 and sets errno to EEXIST if the specified
|
|
* symbolic link already exists.
|
|
* 3) symlink(2) returns -1 and sets errno to EFAULT if the specified
|
|
* file or symbolic link points to invalid address.
|
|
* 4) symlink(2) returns -1 and sets errno to ENAMETOOLONG if the
|
|
* pathname component of symbolic link is too long (ie, > PATH_MAX).
|
|
* 5) symlink(2) returns -1 and sets errno to ENOTDIR if the directory
|
|
* component in pathname of symbolic link is not a directory.
|
|
* 6) symlink(2) returns -1 and sets errno to ENOENT if the component of
|
|
* symbolic link points to an empty string.
|
|
*
|
|
* Expected Result:
|
|
* symlink() 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>
|
|
* symlink03 [-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 John George
|
|
* -Ported
|
|
*
|
|
* Restrictions:
|
|
* This test should be executed by 'non-super-user' only.
