I dislike "limited", I would prefer to write read(n) for "limited", and read() for "unlimited".

Can you try to compute result from avail and request? result = min(avail, result, 5), no?

+1, we can do that. But I was thinking that expected_read_size when mentioned explicitly as it is done right now, would be better for future reference.

Please use a constant instead of 0x81, like:
UNUSED_BYTE = 0x81
(define in this function, no need to declare it at the module scope.)

Oh, GitHub merged the two commits into a single one and chose to use Sanyam Khurana as the author. Hopefully, I wrote both names in the commit message ;-) (I edited manually the commit message before merging.) |
