Hi,

I am developing a real time application

I open /dev/audio with this command

int fd=open("/dev/audio",O_WRONLY);

sometimes it opens in the first attempt but most of the time
the opening fails...so currently i m using this code to open the device

while (fd < 0 )
{
fd=open("/dev/audio",O_WRONLY);

}

it does work but mostly it takes a very long time (more than a minute)...
to open this device. (i know the reason i.e. cz of that loop).

Is there any method available through which i could open this device for writing (playing) on first attempt

I would like to mention that currently i am using to ioctl() call for any purpose

Thank you

The first thing you need to do is find out why the call is failing. #include errno.h and string.h, and set errno = 0 before the call to open(). Then, if the open() fails, call something like printf("%s\n",strerror(errno));

You'll find a list of possible errors, and what they mean, in the man-page for open Hope that's of some help,
