Detailed Description

audsrv source compatibility for the audio library.

Code written against the audsrv API builds and runs on top of audio without changes. Streaming maps onto the audio stream, samples onto audio sounds and channels. CD audio is not supported and reports AUDSRV_ERR_NO_DISC. Moving from audsrv to audio lists each call with its audio equivalent and the differences.

Typedef Documentation

audsrv_adpcm_t

typedef struct audsrv_adpcm_t audsrv_adpcm_t

A loaded ADPCM sample. Treat it as opaque: audsrv_load_adpcm() fills it and the other calls read it.

audsrv_callback_t

typedef int(*) audsrv_callback_t(void *arg)

Callback type for audsrv_on_fillbuf() and audsrv_on_cdda_stop().

Definition at line 63 of file audsrv.h.

audsrv_fmt_t

typedef struct audsrv_fmt_t audsrv_fmt_t

Stream format: output frequency in Hz, bits per sample (8 or 16), channels (1 or 2).
