 * 
 *    Rev 1.3   05 Mar 1996 11:06:12   BG
 * removed hdParmBlock parm from ScanCommon() prototype. This is
 * for template scanning to docs.
 * 
 *    Rev 1.2   22 Feb 1996 14:54:22   BG
 * Makes it all work...
 * 
 *    Rev 1.1   25 Aug 1995 19:24:04   KFS
 * added struct typedef for the ScanCheckTypeWithExt() so can get back
 * filetype along with size. Type needed for verifying multipage files are
 * supported.
 * 
 *    Rev 1.0   20 Jul 1995 16:31:46   KFS
 * Initial entry
 * 
 *    Rev 1.2   28 Apr 1995 16:57:50   KFS
 * Added prototype for IsMultipageFile(), used to check whether user requested
 * and can do a multipage file (need to add code to function to check file
 * type so the flag is truly valid, this version only checks if requested).
 * 
 *    Rev 1.1   30 Aug 1994 12:42:40   KFS
 * 1. added check in comments to file,
 * 2. added internal code prototypes for different c modules for log file
 *    functions
