Routine Description:
This routine returns a pointer to the first character in the
filename part of the supplied path. If only a filename was given,
then this will be a pointer to the first character in the string
(i.e., the same as what was passed in).
To find the filename part, the routine returns the last component of
the string, beginning with the character immediately following the
last '\', '/' or ':'. (NB NT treats '/' as equivalent to '\' )
Arguments:
FilePath - Supplies the file path from which to retrieve the filename
portion.
Return Value:
A pointer to the beginning of the filename portion of the path.
