** Name: select2.c
|
|
**
|
|
** Description: Measure PR_Select and Empty_Select performance.
|
|
**
|
|
** Modification History:
|
|
** 20-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
|
|
** The debug mode will print all of the printfs associated with this test.
|
|
** The regress mode will be the default mode. Since the regress tool limits
|
|
** the output to a one line status:PASS or FAIL,all of the printf statements
|
|
** have been handled with an if (debug_mode) statement.
