Subject: Use strdup instead of SWIGRegisterStringCallback_NDalic called
X-Git-Tag: dali_2.3.12~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F51%2F306351%2F2;p=platform%2Fcore%2Fuifw%2Fdali-csharp-binder.git

Use strdup instead of SWIGRegisterStringCallback_NDalic called

Let we use SWIG_csharp_string_callback as strdup, instead of SWIGRegisterStringCallback_NDalic registered callback.

duplicated string's reference will be released automatically at C# managed memory side. So strdup has
no problem for natural cases.
