Unclear how a client would cancel the parser

[tciuro]

Hello,

I haven't being able to find information about how to cancel the parser. I've seen vague comments like "returning 0 from a callback", but nothing more.

Can someone provide a small snippet showing how a client would cancel the parser? Thanks!

Returning 0 from the callback is quite specific and complete. That's all you need to do to cancel the parser.
