|
* DATE STARTED : 08/11/93
|
|
*
|
|
* INITIAL RELEASE : UNICOS 7.0
|
|
*
|
|
* TEST CASES
|
|
*
|
|
* 1.) test close-on-exec with a regular file
|
|
* 2.) test close-on-exec with a system pipe
|
|
*
|
|
* INPUT SPECIFICATIONS
|
|
*
|
|
* Standard arguments accepted by parse_opts(3).
|
|
*
|
|
* The -t (timing) and -e options apply to the fcntl(.., F_SETFD, ..)
|
|
* system call.
|
|
*
|
|
* -T fd : If this option is given, the program runs as "test_open",
|
|
* testing <fd> to see if it is open or not and exiting
|
|
* accordingly:
|
|
* 0 not open (EBADF from fcntl(..., F_GETFD, ...))
|
|
* 3 no error from fcntl
|
|
* errno fcntl returned an error other than EBADF
|
|
*
|
|
* -F name : File to open. Must be an absolute path
|
|
* and the file must be writable;
|
|
* -n program: path to the 'test_open' program
|
|
*
|
|
* OUTPUT SPECIFICATIONS
|
|
* This test uses the cuts-style test_res format output consisting of:
|
|
*
|
|
* test-name PASS/FAIL/BROK message
|
|
*
|
|
* the message will tell what type of test and, if it failed, indicate
|
|
* what the failure was.

*
|
|
* If this test is not called with a full pathname, it must be able
|
|
* to find itself on $PATH

|
|
* INTERCASE DEPENDENCIES
|
|

|
|
* DETAILED DESCRIPTION
|
|
*
|
|
* Setup:
|
|
* Setup signal handling.
|
|
* Create and make current a temporary directory.
|
|
* Open a regular file for writing
|
|
* Create a system pipe
|
|
* Create a named pipe and open it for writing
|
|
*
|
|
* Test:
|
|
* Set the file descriptor for close-on-exec
|
|
* Fork
|
|
* Child execlp's the program "test_open".
|
|
* If the exec fails, exit "2"
|
|
* Parent waits
|
|
* Report results.
|
|
*
|
|
* Cleanup:
|
|
* Close file and pipes
|
|
* Remove the temporary directory
