[flac-dev] Newbie question about those callbacks

For instance the write_callback thing:
client_data – can it be a pointer to just about anything? For instance
a pointer to a two-dimensional array?
Are those FLAC-WAV and WAV-FLAC examples the only examples available?
What would be the best approach to read a FLAC file to an array of
some kind? Passing a pointer to the array as ”client_data”? I'd like
to use a two-dimensional array, but it's a little tricky (for a
newbie) to pass to functions as a pointer.
It seems like the audio data is passed to the write_callback in a
small buffer. A very small buffer, in fact, only a little more than
4000 frames in my case. Is that to keep the memory usage low?
I can't work directly with the buffer anyway, since I need to
manipulate things ”between the buffers”. That is, if I find something
in the beginning or end of the buffer, I need to manipulate data that
is no longer available in the buffer. That's why I need to read the
whole file into an array.
Maybe I should just do something else, I'm probably too stupid for
these things anyway. Or too old. Or both.
Thanks for listening, you don't need to reply to this crap, sorry.
