Hi all
I have a function which its return value is okay in debugging mode but when I run .exe alone the value seems(msg value) random.

What I have tried:

My function

void recv(int &id, char * msg, int & len)
{
//full msg buffer and len
}

That function does not produce a return value.

You should look at proper variable initialization (as rule, you should initialize all of your variables). While debug builds put zeroes in uninitialized variables, in release build you find garbage inside them.
