示例#1

文件： vnet.c 项目： orumin/openbsd-efivars

void

	int err;

	err = ldc_send_unreliable(lc, msg, len);
	if (err)

示例#2

文件： vdsp.c 项目： DavidAlphaFox/openbsd-kernel

			 * Seems like the hypervisor doesn't actually
			 * generate interrupts for transmit queues, so
			 * we specify a timeout such that we don't
			 * block forever.
