passing struct members to execlp issues
I am trying to pass multiple args to g_signal_connect through a struct and it's members. I think the problem lies with execlp. I am trying to pass the struct members to it but I keep getting errors.
No matter how I format execlp and the struct args, I always get an error. I am beyond stumped!
The current error I receive is Bad address. Like I have said before, no matter how I format execlp, I receive some sort of error. Thank you in advanced.
