Hello!
If program is blocked on snd_rawmidi_read and device is disconnected,
it waits infinitely.
Is this an intentional behaviour?
Trying to read ctl device with read() yeilds the same results.
Test programs attached.
Regards,
Dmitry.
P.S. I'm not a subscrber, please cc me in your replies.
#include <alsa/asoundlib.h>
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int res;
char c;
snd_rawmidi_t *m = NULL;
printf("opening %s: ", argv[1]);
res = snd_rawmidi_open(&m, NULL, argv[1], 0);
printf("%s\n", snd_strerror(res));
printf("reading: ");
res = snd_rawmidi_read(m, &c, 1);
printf("%d\n", res);
return 0;
}
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
int res;
int fd;
char c;
printf("opening %s: ", argv[1]);
res = fd = open(argv[1], O_RDONLY);
printf("%s\n", fd<0 ? strerror(errno) : strerror(0));
printf("reading: ");
res = read(fd, &c, 1);
printf("%d\n", res);
return 0;
}
