[Chicago] Passing structure

[Daniel Griffin]

It is a pretty open ended question. Does the C program essentially do:

char * source = (char*)recv(12); // or whatever the size of the struct

or does it use some sort of formatting? If its sending structs then you can
probably use the python struct module and you might have to worry about
endian-ness and structure packing.
