** Source: test1.c
**
** Purpose: Tests the PAL implementation of the fopen function.
** This test simply attempts to open a number of files
** with different modes. It checks to ensure a valid
** file pointer is returned. It doesn't do any checking
** to ensure the mode is really what it claims. And checks
** for a NULL pointer when attempts to open a directory.
