nit: read_cursor? or maybe src_pos?

Done.

looks like this will accept "2...10" as a valid address, even though it is not.

[Ronghua Wu (Left Chromium), 2012/02/28 23:16:57]

Done.

Why do you need to parse the numbers yourself? maybe use strtol() instead?

[Ronghua Wu (Left Chromium), 2012/02/28 23:16:57]

Done.
