FmapFind() would give it a consistent Fmap*() prefix with the other funcs.

[Che-Liang Chiou, 2011/02/14 02:27:53]

Done.

[Che-Liang Chiou, 2011/02/14 02:27:53]

Done.

Retrun->Return

return index into what?

[Che-Liang Chiou, 2011/02/14 02:27:53]

Done.

[gauravsh, 2011/02/10 20:02:05]

still not clear from the comment what |fh| and |ah| here are. 

[Che-Liang Chiou, 2011/02/14 02:27:53]

Done.

P.S. They are FmapHeader and FmapAreaHeader.
