C++ (Cpp) VDev::ioctl Beispiele

Beispiel #1

Datei: vdev_posix.cpp Projekt: FireRick/Firmware

int px4_ioctl(int fd, int cmd, unsigned long arg)
{
	PX4_DEBUG("px4_ioctl fd = %d", fd);
	int ret = 0;
        if (valid_fd(fd)) {
		VDev *dev = (VDev *)(filemap[fd]->vdev);
		ret = dev->ioctl(filemap[fd], cmd, arg);
	}
	else { 
                ret = -EINVAL;
        }
	if (ret < 0) {
		px4_errno = -ret;
	}
	
        return (ret == 0) ? PX4_OK : PX4_ERROR;
}
