Thread: what is size_t?

thanks for the link, it was very descriptive, that was a site I hadn't come accross before.

Code:

memcpy(&dst[i], &object->broiled, sizeof object->broiled);
   i += sizeof object->broiled;

I'm a bit confused as to what the function of i is here - I can see that the memcpy transfers the contents of each member to consecutive array indexes

Hard to say w/o looking at the declaration of the struct object and array dst[] as i is being incremented by sizeof broiled which is an element of the struct object.

whats the purpose of size here, and why is it decremented?

Again hard to say without its proper context. Looks like it is displaying bytes stored in variable object though decrementing size at each step until it becomes zero for a terminal condition may not be a good idea. Perhaps byte <= size maybe a better choice for the terminal condition but then again it is probably best reviewed in context.
