gSOAP: Obtaining IP to the client when thread pool processing is implemented

Problem:

Ip! is not available to clients when processing client requests using the thread pool

Reason:

Since the Server_loop note loop only adds the connection word sock to the queue, there is no client IP, so each queue callback function can only get sock connection word, no client IP
Workaround:In the queue sock joins the IP also added to the IPs queue, the IPs queue length and queue, and the data stored in the same subscript, take sock processing also take the IP out, you can get the client IP
steps:Define a variable that holds the IP address globally [CPP]View Plaincopyprint?

1. static unsigned long ips[max_queue];

    Static unsigned long ips[max_queue];
