Most of this can be traced back to Mike being overly snippy, which he
certainly was. Also, when you first described what you were doing, A
few details were missing that got filled in later in the conversation,
and that crossed unworkable suggestions that were still pouring in.
Regardless, what Conrad and I both suggested does give you exactly
what you want (using callbacks), portably, predictable, maintainably
and reliably, in under a page of C. Striking on that exact solution
without any additional pain does require someone very familiar with
libvorbisfile, which Conrad and I are (I wrote it and Conrad has
written a workalike). This usage of the interface has been envisioned
(and intentional) from the beginning.
You have a simple desired technical application, and at this point,
you have a simple, correct and complete technical solution. Hopefully
that more or less puts things right.
