Your endMCastAddrDel( ) must also reconfigure the driver (in a
hardware-specific way) so that the driver longer receives frames with the
specified address.
Getting the Multicast Address Table: endMCastAddrGet( )
Your endMCastAddrGet( ) must get a table of multicast addresses and return it in
the buffer referenced in the pMultiTable parameter. These addresses are the list of
multicast addresses to which the interface is currently listening. Your
endMCastAddrGet( ) must take the following form:
STATUS endMCastGetAddr
(
void* pCookie,
MULTI_TABLE* pMultiTable
)
To get the list of multicast address, use the routines provided in etherMultiLib.
This function should return OK or ERROR. If an error occurs, it should set errno.
The parameters are:
pCookie
Passes in a pointer to the END_OBJ structure you returned from your
endLoad( ).
pMultiTable
Passes in a pointer to a buffer. This is an output parameter. Your
endMCastAddrGet( ) must write a MULTI_TABLE structure into the
referenced buffer. end.h defines MULTI_TABLE as follows:
typedef struct
{
long len; /* length of table in bytes */
char *pTable; /* pointer to entries */
} MULTI_TABLE;
Modify the len member of the MULTI_TABLE to indicate just how many
addresses you are returning. Write the addresses to the buffer referenced in the
pTable member of the MULTI_TABLE.
