The API here isn't very generic; it requires the caller to have formatted the GPT entirely by itself, which means having complete knowledge of how to lay out a GPT header and partition table entry. Right now, all that knowledge is contained inside the implementation of the "gpt" command - what if some other unrelated code wanted to write a GPT; it'd have to duplicate everything.
I was thinking of a much more generic interface, where each partition is described using abstract structs, and the creation of the actual on-disk layout is handling inside the set_gpt_table() function. That would presumably allow the same abstract structs to be passed to e.g. set_mbr_partition_table() and a generic "ptable create" command to be created.
