If you use ShellExecuteEx(...) in Windows and set the fMask flag to SEE_MASK_NOCLOSEPROCESS, then you should get the the process handle of the WinZip process. Then you can use WaitForSingleObject and wait until the process has completed.In UNIX you can use spawn() and join() to wait for the external binary's completion and then read its results.

you can use mono (.Net on Linux) to develop remoting application and run it on different machine.

你是想CALL一个EXTERNAL LIBRARY(.so)里面的函数还是要调用一个LINUX程序？

Nothing with C++, just fork and call, if you need read output, you may need dup2() function
