Re: ioctl to set mixer volume

[Alain De Vos via Digitalmars-d-learn]

Correct, then i have :
```
import std.stdio: writeln;
import core.sys.posix.fcntl: open,O_RDWR;
import core.sys.posix.unistd : close;
import core.sys.posix.ioctl: ioctl;
import core.stdc.config: c_ulong;

void main() {
        writeln("Set vol to max");
        char *mixerdev=cast(char *)"/dev/mixer";
        int mode=O_RDWR;
        int mixfd=open(mixerdev,mode);
        writeln(mixfd);
        c_ulong fun=3221507328;
        int vol=255*255+255;
        ioctl(mixfd,fun, &vol);
        close(mixfd);
}

```
