DWORD APIENTRY DhcpRosGetAdapterInfo ( DWORD  AdapterIndex,
PBOOL  DhcpEnabled,
PDWORD  DhcpServer,
time_t *  LeaseObtained,
time_t *  LeaseExpires 
)

Get DHCP info for an adapter

Parameters
[in]AdapterIndexIndex of the adapter (iphlpapi-style) for which info is requested
[out]DhcpEnabledReturns whether DHCP is enabled for the adapter
[out]DhcpServerReturns DHCP server IP address (255.255.255.255 if no server reached yet), in network byte order
[out]LeaseObtainedReturns time at which the lease was obtained
[out]LeaseExpiresReturns time at which the lease will expire
Returns
non-zero on success
Remarks
This is a ReactOS-only routine
