Description

I made this little plugin to be able to check for TCP ports that our server software can use. There is currently only one function that checks if a port is already in use or not, but it is useful.

Sample Usage

validate_port:
  TCP::CheckPort $1
  Pop $0
  StrCmp $0 "free" port_ok
  StrCmp $0 "socket_error" socket_error
  StrCmp $0 "inuse" socket_inuse
  Goto port_ok
socket_inuse:
  MessageBox MB_OK "The Port is in use by another application."
  Abort
socket_error:
  MessageBox MB_OK "Invalid TCP Port number. It should be an integer between 1 and 65535."
  Abort
port_ok:
