Subject: [PATCH] alsactl/info.c: fix conditionals on __ALSA_PCM_H and
|
|
__ALSA_RAWMIDI_H
|
|
|
|
Commit bbc74a61ac7c35e506c3d7f76ecf943cb55736a6 ("alsactl: implement
|
|
'info' command") implemented an alsactl info command. In this
|
|
implementation, there was an attempt to properly address optional
|
|
features from alsa-lib by using conditions on __ALSA_PCM_H,
|
|
__ALSA_RAWMIDI_H.
|
|
|
|
Unfortunately, this attempt does not work entirely: only the code
|
|
inside pcm_device_list(), rawmidi_device_list() was conditionally
|
|
compiled, but their very prototype also use type definitions provided
|
|
in pcm.h and rawmidi.h. So really, it's the entire function that needs
|
|
to be conditionally implemented.
|
|
|
|
Also, snd_rawmidi_stream_name() was not handled properly, for the same
|
|
reason.
|
|
|
|
This commit implements pcm_device_list() only if __ALSA_PCM_H is
|
|
defined, and implements snd_rawmidi_stream_name() and
|
|
rawmidi_device_list() only if __ALSA_RAWMIDI_H is defined.
|
|
|
|
general_card_info() is modified to not call the PCM or raw MIDI
|
|
functions when support is not available.
