[Flac] Making the FLAC decoder work without callbacks

[Ruchir Gulati]

Hi,

We are trying to port FLAC-1.2.1 decoder on a trimmed down MontaVista 
Linux Kernel. This means that we will not be able to support Callbacks in 
our program. The decoder needs to simply read flac encoded data from a 
file, decode it, and play write the decoded PCM to the sound driver for 
playing it.
I am looking to make a very simple application which uses the libFLAC.lib 
static library and calls the following functions to do this task:
- FLAC__stream_decoder_new
- FLAC__stream_decoder_set_md5_checking
- FLAC__stream_decoder_init_FILE
- FLAC__stream_decoder_process_single (inside a while<no. of frames> loop)
- FLAC__stream_decoder_delete

All of this happens without resorting to callbacks. Even though it seems 
from the documentation that this is a possibility with the given APIs, I 
am not able to make it work. Does anyone have any ideas about how I should 
go about doing this?

Any help will be greatly appreciated!


Thanks & regards,
