Re: [flac-dev] Newbie question about those callbacks
2013/2/10 Erik de Castro Lopo mle...@mega-nerd.com: Johnny Rosenberg wrote: For instance the write_callback thing: client_data – can it be a pointer to just about anything? I assume you mean: https://www.xiph.org/flac/api/group__flac__stream__decoder.html#ga13 which defines the type: typedef FLAC__StreamDecoderWriteStatus (* FLAC__StreamDecoderWriteCallback) (const FLAC__StreamDecoder *decoder, const FLAC__Frame *frame , const FLAC__int32 *const buffer[], void *client_data) Yes, client_data can point at anything. You the callee are responsible to cast your pointer_to_anything to and from 'void*' Thanks. That explains the following line in the write_callback function one of the the two examples I found: FILE *f=(FILE*)client_data; For instance a pointer to a two-dimensional array? Yes. They can even be NULL. Yes, I saw that in the other example… :) Whatever pointer you pass as the client_data parameter in the finction FLAC__stream_decoder_init_stream () will be passed back to you in the callbacks client_data. Are those FLAC-WAV and WAV-FLAC examples the only examples available? There are examples in the examples/ directory of the FLAC source code tarball. They are in Git here: https://git.xiph.org/?p=flac.git;a=tree;f=examples/c;h=dbcb345dcd699ca3f1a1b1d334f5a48d45385558;hb=HEAD Ok, that's the two examples that I already know about. I will not waste more time looking for more examples then. Thanks. 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. I agree, coding to the FLAC API is not something that is easy or obvious for a newbie C programmer. No, I realised that at an early stage. The future will show if I will give up or not… I am sure I will finish my code, but I'm not sure whether I will use libflac or something else. Thanks for helping.
