Hi,
I want to check different devices on status and if media is insert.
Now i have tried followed
errno = 0;
fd = open( device , O_RDWR|O_NONBLOCK );
if( fd < 0 ) {
if( errno == ENOENT ) return "3,0,0,0" ;
i = 1 ;
errno = 0;
fd = open( device , O_RDONLY|O_NDELAY );
if( fd < 0 ) {
return "2,0,0,0" ;
}
}
sprintf( parmstring , "%d,0,0,0" , i );
return parmstring ;
But if I check a cd-rom device without any insert media, i get the parameter
1,0,0,0.
Exist any other easy way to check different devices (disk, floppy, tape, cd,
zip) or should i check the status of the devices with special ioctl -
commands ?
Thnx
Alex
