IPV4 recvfrom() thru which network interface

Dear all

My Win 98machine is configured with 2 NICs connecetd to diferent LANs. If a
datagram packet is received to by muticast listnener socket joined to
INADDR_ANY group in my machine with 2 NICs (both interfaces having an IPV4
address each, other than loop backs), a winsock recvfrom() can get me the
address from which the packet came from. But is there a way to identify
through which interface in my machine?

Plese reply if any clarification needed.

Thanks in advance for all expert advices
