# Windows Sockets Return Values

If a Windows Sockets function succeeds, it returns 0. If a VuGen error occurs, an LRS return code is issued. If an error occurs with a socket, it returns one of the Windows Sockets error codes.

To retrieve the error code, evaluate the return value of the function. For example:

rc = lrs_close_socket("socket5");

if (rc==0)

lr_output_message("Socket 5 was successfully closed ");

else

lr_output_message("An error occurred while closing the socket, Error Code: %d", rc);

VuGen returns the following error and warning codes during replay of Windows Sockets script:
