quotex.cpp

linux下简单对象应用协议的开发库

/*	quotex.cpp
	This example is both a SOAP service and a client application.
	As a CGI program, it will serve currency-converted stock quote requests.
	As a client, it will return the currency-converted stock quote given as
	arguments to the program on the command-line. For example
	> quotex AOL uk
