The boost thread uses the class member function method with parameters.

Assume that the VZController class has the following member functions: [cpp] void downloadData (std: string filename); Put the downloaded data part in a separate thread to execute the download process, but the file must be stored in the main thread. How can this problem be solved? You can use boost: function and boost: bind to generate a packaging function object, and then bind parameters to the function object. The Code is as follows: [cpp] # include <boost/bind. hpp> # include <boost/function. hpp> # include <boost/thread. hpp>... std: string localFileName = "D: \ temp \ dl. dat "; boost: function <void (std: string)> memberFunctionWrapper (boost: bind (& VZController: downloadData, this, _ 1); boost :: thread downloadThread = new boost: thread (boost: bind (memberFuncti OnWrapper, localFileName);... if you want to pass multiple parameters, you can easily change the definition of the function object. "Boost thread library learning notes" (http://www.cnblogs.com/younes/archive/2010/06/06/1752745.html) also introduced a method to pass parameters to the thread function, but more trouble than this method, I have never tried whether it can be used in member functions of class objects.
