asterisk c-agi 提供c 语言接口的例子

*********************************
V.7 - Changes
*********************************
Nov 13, 2006 - Fixed bug in AGITool_sendcmd(). Was loosing last char in data field.

*********************************
V.6 - Changes
*********************************
Sep 06, 2006 - Made fastcagi support command line arguments. Also using read rather than fgets so
					it won't drain the stdin buffer.
				 - CAGI now checks return values of fgets in Init in case stdin pipe is lost.

*********************************
V.5 - Changes
*********************************
Sep 04, 2006 - Made AGITool_ListAddItem() use malloc instead of static buffer. Allow longer variable name/value
				 - Added fastcagi that serves up AGI apps for fast AGI execution. It will serve AGI's written in any 
				 	language as long as it is executable via exec().
					
*********************************
V.4 - Changes
*********************************
Mar 10, 2006 - Fixed bug with sendcmd where fgets would get a NULL and strlen(str) would core. would only 
               happen if program tried to stick around after SIGHUP. fgets() returned NULL cause stdin was gone
             - Also implemented some EXEC functions for SetLanguage, Goto, and AbsoluteTimeout.

*********************************
V.3 - Changes
*********************************
Oct 03, 2005 - Fixed bug with send_cmd. Data is now properly filled. 
             - Added raw field to result struct to get raw data send by asterisk.
             - Added AGITool_get_variable2().

Sept 29,2005 - Added AGITool_exec_dial(). Thanks to Raymond Chen for working on and testing.

*********************************
V.2 - Changes since last release.
*********************************

Jul 7 - Added some #defines for spool and temp dir's that were in phpagi. Nice to have
      - Added a check for null in strim. Anything that stops core dumps. not likely, but good to check.

Jun 5 - Changed the command AUTOHANGUP to "SET AUTOHANGUP".  I am not sure if I messed this up, or if it just changed.  hope it works
Apr 14 - Changed License to LGPL.  Not sure why, people just like it better

**********************************
V.1 - Initial checkin
