Trying to figure out name of data struct
While going through some code, I came accross this block of code:
struct option options = {
{"help", 0, 0, HELP_OPTION},
{"minor", 1, 0, MINOR_OPTION},
{"dac", 1, 0, DAC_OPTION},
{0, 0, 0, 0}
};
I know what a struct is, but I have never seen a "{0, 0, 0, 0}" data struct. Does anyone know what the name for the "{0,0,0,0}" data struct is?

I'm not sure what you mean by the name of the data struct. It's just like the others in the array except the values are 0.

The code simply defines an array that contains several instances of option structures. In this case, the { 0, 0, 0, 0 } is probably used to signify that it is the last item in the array (since C arrays don't have a length property).
As far as the name, it is unnamed. You can reference this structure from code using options[3].
