rearpwhohas(9r)
NAME
rearpwhohas - Network: Broadcasts an ARP packet
SYNOPSIS
void rearpwhohas(
struct arpcom *ac );
ARGUMENTS
ac Specifies a pointer to an arpcom data structure. This data structure
defines information that is shared between the network layer and the
device driver.
DESCRIPTION
The rearpwhohas() routine broadcasts an ARP packet to all hosts that
currently have the driver's associated IP address in their ARP tables. The
broadcast is made only if the IP address is configured. The system marks
the IP address as configured by setting the ac_flag member of the
associated arpcom data structure to the bit value AC_IPUP.
The rearpwhohas() routine obtains the configured IP address from the
ac_bcastaddr member of the arpcom data structure.
NOTES
You use the rearpwhohas() routine only when a LAN driver changes its
physical address. Make sure that this interface is called without any locks
held.
RETURN VALUES
None
