Linux Network Programming: send() crashes program

[kardon33]

Hello Bytes,

I am writing a network program in c++ on Linux Debian x86.

I am using tcp sockets to communicate with other processors all very standard stuff.

However Im stuck at one hump, when I try to call send() on a socket where the other machine loss power of crashed. Send crashes my program, no return of -1 just crash with no output.

My Send Command:

 if (send(vars->Nodes[n].sockfd, buf3, strlen(buf3), 0) == -1) {
       vars->Nodes[n].ready = 0;
       vars->Nodes[n].connected = 0;
       perror("sendTimeCode");
 }

Any thoughts?

Nevermind, my dumb mistake.

It was throwing a connection reset by peer error but I missing it and the next time I called send() it crashed which is ok.
