PSCP multi-threaded transfer files

As I said earlier, PSCP does not support multi-threading, so we specifically implemented a

The program is divided into three parts:

1, initialization of various parameters, involving the use of getopt function

2. Define SCP, implement IP transfer and copy remotely

3, start multi-threaded call SCP, involving multi-threaded start and wait thread end
