Hi all, background info: i''m using win32, async sockets... i can connect, recv, send, accept, close sockets // psuedo code struct packet1 { char userName[30]; char userPass[30]; } //size 60 bytes struct packet2 { int playerX; int playerY; } // size 8 bytes i know to send the struct you would do this: send(socket,(char*)&packet1,sizeof(packet1),0); but, if the server is blind, how can it distenguish between the two packets? I.E. i have read a tutorial on how to build a HTTP server/client, and the server and client can distuenquish between the two because they read the char arry to find sentienals. but u can''t do that w/ints... Any help would be greately appriciated, and i''m sure its something simple i can''t think of or find THX
