The Advanced Linux Sound Architecture (ALSA) - utilities
52c9cc9571
Add a command line option to automatically exit after recording a fixed number of MIDI events. This allows a program using arecordmidi to expect a MIDI file to be written automatically when the specified number of events have been received, instead of having to send a SIGINT or SIGTERM programmatically. It also avoids the need to have the arecordmidi process running in the background, and then constantly stat the output file to check if any bytes have been written to it (this makes for less predictable and longer-running tests). This functionality finds use in Chrome OS functional testing, since having to send SIGTERM/SIGINT programmatically and then wait for the output file adds unpredictability and delay to the tests. The addition of this command-line option should (hopefully) not break any existing usage. Signed-off-by: Prashant Malani <pmalani@chromium.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> |
