** This routine returns the longest pathlength possible from the input path
** It assumes that the input path is a buffer that it can extend by a
** wildcard '\*' to search the file, if it is a directory.
** The input path must be fully qualified, eg: "c:\winnt\system32\kernel32.dll"
**
** Input:
**      pPath   fully qualified Pathname
**      pCch    pointer to length of pathname
** Returns:
**      TRUE    succeeded, pCch contains length
**      FALSE   error occurred
