alsa-lib/include/local.h
Jaroslav Kysela bf780a25a5 Added argument handling for the slave PCMs.
The configuration root (snd_config) can be specified for the internal routines.
The pcm_hooks code was recoded (independent code moved to control/setup.c).
Improved the pcm_multi plugin (added master configuration).
