 NAME
dlpi_enabmulti, dlpi_disabmulti - enable or disable DLPI multicast messages
for an address

 SYNOPSIS


cc [ flag... ] file... -ldlpi [ library... ]
#include <libdlpi.h>

int dlpi_enabmulti(dlpi_handle_t dh, const void *addrp,
 size_t addrlen);






int dlpi_disabmulti(dlpi_handle_t dh, const void *addrp,
 size_t addrlen);




 DESCRIPTION

The dlpi_enabmulti() function enables reception of messages destined to
the multicast address pointed to by addrp on the DLPI link instance
associated with DLPI handle dh. The DLPI link instance will
pass up only those messages destined for enabled multicast addresses. This
operation can be performed in any DLPI state of a handle.


The dlpi_disabmulti() function disables a specified multicast address
pointed to by addrp on the DLPI link instance associated with
DLPI handle dh. This operation can be performed in any DLPI
state of a handle.

 RETURN VALUES

Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is returned,
errno contains the specific UNIX system error value. Otherwise, a
DLPI error value defined in <sys/dlpi.h> or DLPI_EINHANDLE is
returned.

 ERRORS

DLPI_EBADMSG


Bad DLPI message





DLPI_EINHANDLE


Invalid DLPI handle





DLPI_EINVAL


Invalid argument





DLPI_ETIMEDOUT


DLPI operation timed out
