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

125 * added header write/update public methods
127 * Revision 1.26 2002/09/29 00:00:08 warmerda
128 * added FTLogical and logical attribute read/write calls
130 * Revision 1.25 2002/05/07 13:46:30 warmerda
