 * $Log: shapefil.h,v $
 * Revision 1.52  2011-12-11 22:26:46  fwarmerdam
 * upgrade .qix access code to use SAHooks (gdal #3365)
 *
 * Revision 1.51  2011-07-24 05:59:25  fwarmerdam
 * minimize use of CPLError in favor of SAHooks.Error()
 *
 * Revision 1.50  2011-05-13 17:35:17  fwarmerdam
 * added DBFReorderFields() and DBFAlterFields() functions (from Even)
 *
 * Revision 1.49  2011-04-16 14:38:21  fwarmerdam
 * avoid warnings with gcc on SHP_CVSID
 *
 * Revision 1.48  2010-08-27 23:42:52  fwarmerdam
 * add SHPAPI_CALL attribute in code
 *
 * Revision 1.47  2010-01-28 11:34:34  fwarmerdam
 * handle the shape file length limits more gracefully (#3236)
 *
 * Revision 1.46  2008-11-12 14:28:15  fwarmerdam
 * DBFCreateField() now works on files with records
 *
 * Revision 1.45  2008/11/11 17:47:10  fwarmerdam
 * added DBFDeleteField() function
 *
 * Revision 1.44  2008/01/16 20:05:19  bram
 * Add file hooks that accept UTF-8 encoded filenames on some platforms.  Use SASetupUtf8Hooks
 *  tosetup the hooks and check SHPAPI_UTF8_HOOKS for its availability.  Currently, this
 *  is only available on the Windows platform that decodes the UTF-8 filenames to wide
 *  character strings and feeds them to _wfopen and _wremove.
 *
 * Revision 1.43  2008/01/10 16:35:30  fwarmerdam
 * avoid _ prefix on #defined symbols (bug 1840)
 *
 * Revision 1.42  2007/12/18 18:28:14  bram
 * - create hook for client specific atof (bugzilla ticket 1615)
 * - check for NULL handle before closing cpCPG file, and close after reading.
 *
 * Revision 1.41  2007/12/15 20:25:32  bram
 * dbfopen.c now reads the Code Page information from the DBF file, and exports
 * this information as a string through the DBFGetCodePage function.  This is 
 * either the number from the LDID header field ("LDID/<number>") or as the 
 * content of an accompanying .CPG file.  When creating a DBF file, the code can
 * be set using DBFCreateEx.
 *
 * Revision 1.40  2007/12/06 07:00:25  fwarmerdam
 * dbfopen now using SAHooks for fileio
 *
 * Revision 1.39  2007/12/04 20:37:56  fwarmerdam
 * preliminary implementation of hooks api for io and errors
 *
 * Revision 1.38  2007/11/21 22:39:56  fwarmerdam
 * close shx file in readonly mode (GDAL #1956)
 *
 * Revision 1.37  2007/10/27 03:31:14  fwarmerdam
 * limit default depth of tree to 12 levels (gdal ticket #1594)
 *
 * Revision 1.36  2007/09/10 23:33:15  fwarmerdam
 * Upstreamed support for visibility flag in SHPAPI_CALL for the needs
 * of GDAL (gdal ticket #1810).
 *
 * Revision 1.35  2007/09/03 19:48:10  fwarmerdam
 * move DBFReadAttribute() static dDoubleField into dbfinfo
 *
 * Revision 1.34  2006/06/17 15:33:32  fwarmerdam
 * added pszWorkField - bug 1202 (rso)
 *
 * Revision 1.33  2006/02/15 01:14:30  fwarmerdam
 * added DBFAddNativeFieldType
 *
 * Revision 1.32  2006/01/26 15:07:32  fwarmerdam
 * add bMeasureIsUsed flag from Craig Bruce: Bug 1249
 *
 * Revision 1.31  2006/01/05 01:27:27  fwarmerdam
 * added dbf deletion mark/fetch
 *
 * Revision 1.30  2005/01/03 22:30:13  fwarmerdam
 * added support for saved quadtrees
 *
 * Revision 1.29  2004/09/26 20:09:35  fwarmerdam
 * avoid rcsid warnings
 *
 * Revision 1.28  2003/12/29 06:02:18  fwarmerdam
 * added cpl_error.h option
 *
 * Revision 1.27  2003/04/21 18:30:37  warmerda
 * added header write/update public methods

 * Revision 1.26  2002/09/29 00:00:08  warmerda
 * added FTLogical and logical attribute read/write calls
 *
 * Revision 1.25  2002/05/07 13:46:30  warmerda
 * added DBFWriteAttributeDirectly().
 *
 * Revision 1.24  2002/04/10 16:59:54  warmerda
