A page is a flexibly allocated structure of bytes, with a count of the number of bytes already allocated (used) and number of bytes available overall (available), with a pointer to the next page, if any. heap_t is a linked list of pages. One may allocate a requested size off the heap which causes one of two things: 1) Either a page already exists with enough space for the requested size, in which case that page's pointer is used as the base for the requested pointer 2) No pages satisfy the requested size, so a new page is allocated which is the new end of the heap.
