Function Documentation

syscall dhcpRecvReply	(	int	descrp,
		struct dhcpData *	data,
		uint	timeout
	)

Wait, with timeout, for a response from a DHCP server and update the DHCP transfer data. The exact behavior of this function depends on the current DHCP client state:

• If in DHCPC_STATE_SELECTING, the client waits until it gets a DHCPOFFER reply from any server.
• If in DHCPC_STATE_REQUESTING, the client waits until it gets a DHCPACK or DHCPNAK reply from the server to which it sent the DHCPREQUEST.

Parameters

[in]	descrp	Network device on which to wait for a response.
[in,out]	data	DHCP transfer data.
[in]	timeout	Milliseconds to wait before timing out.

Returns

OK if successful; TIMEOUT if timed out; SYSERR if other error occurred.
