// normally stb_vorbis uses malloc() to allocate memory at startup,
|
|
// and alloca() to allocate temporary memory during a frame on the
|
|
// stack. (Memory consumption will depend on the amount of setup
|
|
// data in the file and how you set the compile flags for speed
|
|
// vs. size. In my test files the maximal-size usage is ~150KB.)
|
|
//
|
|
// You can modify the wrapper functions in the source (setup_malloc,
|
|
// setup_temp_malloc, temp_malloc) to change this behavior, or you
|
|
// can use a simpler allocation model: you pass in a buffer from
|
|
// which stb_vorbis will allocate _all_ its memory (including the
|
|
// temp memory). "open" may fail with a VORBIS_outofmem if you
|
|
// do not pass in enough data; there is no way to determine how
|
|
// much you do need except to succeed (at which point you can
|
|
// query get_info to find the exact amount required. yes I know
|
|
// this is lame).
|
|
//
|
|
// If you pass in a non-NULL buffer of the type below, allocation
|
|
// will occur from it as described above. Otherwise just pass NULL
|
|
// to use malloc()/alloca()
