Does this help? I'm not sure how much help you need and I don't want to type for 20 minutes if you only need 3 minutes worth of help (laziness factor!)
This answer help me a little bit. But I still have a (small?) problem. For example I tried this:
Client:
-
struct CommandData
-
{
-
int Test1;
-
int Test2;
-
char *Para;
-
};
-
-
CommandData Test;
-
Test.Test1 = 10;
-
Test.Test2 = 33924823;
-
Test.Para = "Hello World!";
-
-
send( Socket, (char *) &Test, sizeof( CommandData ), 0 );
-
Server:
-
struct CommandData
-
{
-
int Test1;
-
int Test2;
-
char *Para;
-
};
-
-
CommandData Test;
-
recv( connectedSocket,(char * ) &Test, 256,0 ); // Whats about the Number 256? What I need to put there?
-
-
printf( "Received:%s-%i-%i\n", Test.Para, Test.Test1, Test.Test2 ); // Output "Received:-10-33924823"
-
Firstly, is this the right way to do this? I'm very frigthend that I maybe receive not all data. And the struct can't be used.
Another problem is that I don't receive the "char *Para". How I send it on the right way? And how portable is this?
Example:
Server Windows - Client Linux System
What will happen? Does it still work?
Thanks for your help :)
