network_send_raw(socket, buffer, size);
With this function you can send a "raw" data packet through the
network. The function takes the socket id to connect through
and then you must supply the buffer id which contains the
data to be sent (for more information on buffers see Reference - Buffers) and finally the
size (in bytes) of the data packet. The data sent is not formatted
by GameMaker Studio 2 in any way and the receiving devices
will get the data as a stream which means you will have to handle
it yourself. The function will return the number of bytes of data
sent, or a number less than 0 if the send has failed.
buff = buffer_load("player_save.dat");
network_send_raw(sock, buff, buffer_get_size(buff));
The above information loads a previously saved buffer data into memory and returns the buffer id to be stored in the variable "buff". This complete buffer is then send as a raw data packet over the network using the socket identified by the variable "sock".
