C language: “can’t bind to the port” problem (Windows)

Sometimes your program process can stuck and trigger error like this:

Couldn’t bind to the port

Ok, we have such check in out sockets C code:

if (bind (socket_desc, (struct sockaddr*)&server_addr, sizeof(server_addr)) < 0)
printf("Couldn't bind to the port\n");

And it return negative value.. How to fix it?

1. find which process using this port via cmd:
   netstat -ano | findstr :<port number>
   For example:
   C:\Users\n>netstat -ano | findstr :2000
   You will see such message:
   TCP 127.0.0.1:2000 0.0.0.0:0 LISTENING 3560
2. last number is ID of process. To kill process:
   taskkill /pid <process ID> /F
   Example:
   C:\Users\n>taskkill /pid 3560 /F
SUCCESS: The process with PID 3560 has been terminated.

Enjoy!
