Hi,
i need some clarifying about how the defines ALSA_PCM_OLD_HW_PARAMS_API etc. behaves.
for alsa-1.x its clear that if the app uses the new api i have to define ALSA_PCM_NEW_HW_PARAMS_API, but what is for the case if i have an app with the new api and the user uses only alsa9? is alsa1.x then backwards compatible?


regards

Zsolt Barat



ALSA_PCM_NEW_HW_PARAMS_API etc. is for use with alsa0.9.x
That define is assumed to be the default for alsa1.x.x

ALSA_PCM_OLD_HW_PARAMS_API is for use with alsa1.x.x to make it behave like "alsa0.9.x without the ALSA_PCM_NEW_HW_PARAMS_API".

Summary: -
To make your code work with bother alsa 0.9.x and 1.x.x, use ALSA_PCM_NEW_HW_PARAMS_API etc. and then write your code to the 1.x.x api.
