TwSMS 發簡訊 (Linux C 版)
台灣簡訊(TwSMS)是國內一家線上傳簡訊的服務商，提供文字簡訊、語音簡訊等服務，價格也很合理，最重要的是有提供 API 介面，方便用戶在自己的程式中加入發送簡訊功能，官網已經有提供不少範例(PHP/ASP/JSP/Java/Perl/VB/BCB/Delphi)，這邊也有 Ruby 的版本，不過就是沒看到 C 的，所以大略寫了一個 Linux C 版本，打算加入自己的嵌入式專題使用。
TwSMS 提供的 API 很簡單，只要由 HTTP 對 API server 發送 Request 即可，接著 server 就會回傳結果。程式先建立一個 socket 連線，然後發送簡訊，最後再擷取回傳碼檢查是否成功。
