- ** 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.
