sock_join_multicast_v6()

Joins a particular multicast IPv6 group.

Description

The sock_join_multicast_v6() function allows a socket to join a specified multicast IPv6 group on a specific interface.

Syntax

  ;;; Joins a particular multicast IPv6 group
  (@interface func (export "sock_join_multicast_v6")
    ;;; Socket descriptor
    (param $fd $fd)
    ;;; Multicast group to joined
    (param $multiaddr (@witx const_pointer $addr_ip6))
    ;;; Interface that will join
    (param $interface u32)
    (result $error (expected (error $errno)))
  )

Parameters

• ctx: A mutable reference to the function environment.
• sock: The socket descriptor.
• multiaddr: A WebAssembly pointer to the IPv6 multicast group to be joined.
• iface: The interface index to join the multicast group.

Return Value

The function returns an Errno value indicating the outcome of the operation. If the operation is successful, Errno::Success is returned. If an error occurs, an appropriate Errno value is returned.

Notes

• The sock_join_multicast_v6() function allows a socket to join a specified multicast IPv6 group on a specific interface.
• The multiaddr parameter specifies the IPv6 multicast group to join.
• The iface parameter specifies the interface index on which to join the multicast group.
• The behavior and limitations of the sock_join_multicast_v6() function may vary depending on the specific runtime environment and underlying networking implementation. It is important to consult the documentation or specifications of the specific environment to understand its behavior in that context.
