Structures

GROUP_FILTER Provides multicast filtering parameters for multicast IPv6 or IPv4 addresses.
GROUP_REQ Provides multicast group information for IPv6 or IPv4 addresses.
GROUP_SOURCE_REQ Provides multicast group information for IPv6 or IPv4 addresses that includes the source IP address.
ICMP_ERROR_INFO Used to store received ICMP error information.
IN_PKTINFO The in_pktinfo structure is used to store received packet address information, and is used by Windows to return information about received packets and also allows specifying the local IPv4 address to use for sending packets.
IN6_PKTINFO The in6_pktinfo structure is used to store received IPv6 packet address information, and is used by Windows to return information about received packets and also allows specifying the local IPv6 address to use for sending packets.
INTERFACE_INFO The INTERFACE_INFO structure is used in conjunction with the SIO_GET_INTERFACE_LIST ioctl command to obtain information about an interface IP address.
INTERFACE_INFO_EX The INTERFACE_INFO_EX structure is used in conjunction with the SIO_GET_INTERFACE_LIST IOCTL command to obtain information about an interface IP address.
IP_MREQ The ip_mreq structure provides multicast group information for IPv4 addresses.
IP_MREQ_SOURCE The ip_mreq_source structure provides multicast group information for IPv4 addresses.
IP_MSFILTER The ip_msfilter structure provides multicast filtering parameters for IPv4 addresses.
IPV6_MREQ The ipv6_mreq structure provides multicast group information for IPv6 addresses.
sockaddr_gen Provides generic socket address information, and is used with the INTERFACE_INFO structure.
SOCKADDR_IN6_LH The SOCKADDR_IN6_LH (ws2ipdef.h) structure specifies a transport address and port for the AF_INET6 address family.
sockaddr_in6_old The sockaddr_in6_old (ws2ipdef.h) structure varies depending on the protocol selected.
SOCKADDR_IN6_PAIR Contains pointers to a pair of IP addresses that represent a source and destination address pair.
SOCKADDR_IN6_W2KSP1 The SOCKADDR_IN6_W2KSP1 (ws2ipdef.h) structure specifies a transport address and port for the AF_INET6 address family.
SOCKADDR_INET Contains an IPv4, an IPv6 address, or an address family.

Enumerations

MULTICAST_MODE_TYPE Specifies the filter mode for multicast group addresses.
