Re: [alsa-devel] [PATCH v4 4/6] core: add API header and driver header files

+struct snd_compr_runtime {

• snd_pcm_state_t state;
• struct snd_compr_ops *ops;
• void *buffer;

Can we define buffer as char *?

• size_t buffer_size;
• size_t fragment_size;

Can we define buffer_size and fragment_size as unsigned items? Can we have negative size here?

• unsigned int fragments;
• size_t hw_pointer;
• size_t app_pointer;
• size_t bytes_written;
• size_t bytes_copied;
• wait_queue_head_t sleep;
