send_data, problem with strings - 02/11/10 05:41
Hi,
I'm having trouble sending a string from one PC to another using the send_data_to or send_data_id commands, I've already posted here but had no replies.
How exactly (needs to be using send_data not send_string as I need to send additional information with the string) do I go about this.
So far I've tried
typedef struct DATA {
int id;
int type;
// char name; //gives me a one char garbled message (as expected) from server to client
// char* name; //sends the correct message, but receives only 1 char, no chars, or crashes client
// char* name; //sending with _chr(msg.name), repeats the above, but never with a crash
// char name[20]; //sends unreadable string using _chr or _str
// char* name[20]; //sends unreadable string
STRING* name; //sends correct message, crashes client
//all messages shown for sending and receiving via update_log()
} DATA;
DATA msg;
here's the code I'm using any insight would be appreciated
NB: you can probably already see I've tried using str_create, str_cpy for the log, but unsure which if i should be using = or str_cpy, both seem to have advantages and disadvantages.
I am able to workaround atm by doing string manipulation before sending and after receving using send_string, but would prefer to use the send_data method.
Many thanks
