Introduction:

twitcurl is a pure C++ library for twitter APIs. twitcurl uses cURL library for handling HTTP requests and responses. twitcurl has been tested on Microsoft Windows, Ubuntu and Debian. In fact, it works just fine on any operating system that supports cURL.

OAuth

twitcurl supports OAuth authorization methods. Check twitterClient example code in trunk section to know about twitcurl OAuth flow. Also, check wiki page for more info: http://code.google.com/p/twitcurl/wiki/TwitcurlOAuthFlow

Source:

twitcurl library source (with Microsoft Visual C++ 6.0 workspace) is available in the repository in "Source" tab. Use SVN or tools like TortoiseSVN (http://tortoisesvn.net/) to check-out and download files. Makefile for Linux distributions in available in svn > branches > libtwitcurl branch in "Source" tab.

See wiki section for more info on building and using twitCurl library. http://code.google.com/p/twitcurl/wiki/WikiHowToUseTwitcurlLibrary

Note:

• twitcurl returns the HTTP responses from twitter.com as it is (i.e. in XML format). You need to have an XML parser such as Xerces (http://xerces.apache.org/xerces-c/) to parse the responses.
• twitcurl uses HMAC_SHA1 from http://www.codeproject.com/KB/recipes/HMACSHA1class.aspx
• twitcurl uses base64 from http://www.adp-gmbh.ch/cpp/common/base64.html
• twitcurl trends APIs return data in JSON format. Check out http://www.json.org/ for C/C++ parsers.

Example:

An example twitter client program using twitcurl as a static library is available in the "Downloads" section.
