* $Log: shapefil.h,v $
* Revision 1.56 2018-08-16 15:39:07 erouault
* * shpopen.c, dbfopen.c, shptree.c, sbnsearch.c: resyc with GDAL
* internal shapelib. Mostly to allow building those files as C++
* without warning. Also add FTDate entry in DBFFieldType
* (see https://github.com/OSGeo/gdal/pull/308). And some other
* code cleanups
*
* Revision 1.55 2016-12-05 18:44:08 erouault
* * dbfopen.c, shapefil.h: write DBF end-of-file character 0x1A by default.
* This behaviour can be controlled with the DBFSetWriteEndOfFileChar()
* function.
*
* Revision 1.54 2016-12-05 12:44:05 erouault
* * Major overhaul of Makefile build system to use autoconf/automake.
*
* * Warning fixes in contrib/
*
* Revision 1.53 2016-12-04 15:30:15 erouault
* * shpopen.c, dbfopen.c, shptree.c, shapefil.h: resync with
* GDAL Shapefile driver. Mostly cleanups. SHPObject and DBFInfo
* structures extended with new members. New functions:
* DBFSetLastModifiedDate, SHPOpenLLEx, SHPRestoreSHX,
* SHPSetFastModeReadObject
*
* * sbnsearch.c: new file to implement original ESRI .sbn spatial
* index reading. (no write support). New functions:
* SBNOpenDiskTree, SBNCloseDiskTree, SBNSearchDiskTree,
* SBNSearchDiskTreeInteger, SBNSearchFreeIds
*
* * Makefile, makefile.vc, CMakeLists.txt, shapelib.def: updates
* with new file and symbols.
*
* * commit: helper script to cvs commit
*
* 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
