From: miker Date: Thu, 25 Oct 2007 12:20:16 +0000 (+0000) Subject: Patch from Scott McKellar to increase const correctness in the JSON parser. X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=0fd36820934ad7d78b1733afa4277e87da2d92fd;p=working%2FOpenSRF.git Patch from Scott McKellar to increase const correctness in the JSON parser. Also made the top level legacy_jsonParseString[Fmt] API const-correct, though this is removed within those wrapper calls to avoid potentially breaking the legacy code. git-svn-id: svn://svn.open-ils.org/OpenSRF/trunk@1114 9efc2488-bf62-4759-914b-345cdb29e865 --- diff --git a/include/opensrf/osrf_json.h b/include/opensrf/osrf_json.h index 5243f03..64844fd 100644 --- a/include/opensrf/osrf_json.h +++ b/include/opensrf/osrf_json.h @@ -73,7 +73,7 @@ GNU General Public License for more details. struct jsonParserContextStruct { int state;
