/*
** File:	prftest1.c
** Description:
**     This is a simple test of the PR_snprintf() function defined
**     in prprf.c.
**
** Modification History:
** 14-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.
