clientcreate() returns 0

hey there,

i wrote this piece of code in the OnRunStart trigger. i wanted to initiate a socket communication with a server written in C#

int socknum = clientcreate();
string host = "127.0.0.1";
int sockport = 13000;
clientconnect(socknum, host, sockport);
clientsend(socknum,"this is flexsim");

but the cliencreate(); always returns 0. In the command help is written that if an error occurs, this function returns 0. but what kind of error? all logs are also empty.

I'm using FlexSimn 7.0.6.

Thanks for helping!

Hello Simon,

I have not any experience in socket communication, I was just looking for threads:
Perhaps flexsim still expects the communication from a c++ node rather than a flexscript node mentioned in Nico's thread.

finally found the solution. socketinit() has to be called first - some background processes are initalized there. now it works fine!

socketinit();
int socknum = clientcreate();
string host = "127.0.0.1";
int sockport = 13000;
clientconnect(socknum, host, sockport);
clientsend(socknum,"this is flexsim");
