Function Documentation

apr_status_t apr_mcast_hops ( apr_socket_t * sock,

apr_byte_t ttl

)

Set the Multicast Time to Live (ttl) for a multicast transmission.

Parameters:: sock The socket to set the multicast ttl

ttl Time to live to Assign. 0-255, default=1

Remarks:: If the TTL is 0, packets will only be seen by sockets on the local machine, and only when multicast loopback is enabled.

apr_status_t apr_mcast_interface ( apr_socket_t * sock,

apr_sockaddr_t * iface

)

Set the Interface to be used for outgoing Multicast Transmissions.

Parameters:: sock The socket to set the multicast interface on

iface Address of the interface to use for Multicast

apr_status_t apr_mcast_join ( apr_socket_t * sock,

apr_sockaddr_t * join,

apr_sockaddr_t * iface,

apr_sockaddr_t * source

)

Join a Multicast Group

Parameters:: sock The socket to join a multicast group

join The address of the multicast group to join

iface Address of the interface to use. If NULL is passed, the default multicast interface will be used. (OS Dependent)

source Source Address to accept transmissions from (non-NULL implies Source-Specific Multicast)

apr_status_t apr_mcast_leave ( apr_socket_t * sock,

apr_sockaddr_t * addr,

apr_sockaddr_t * iface,

apr_sockaddr_t * source

)

Leave a Multicast Group. All arguments must be the same as apr_mcast_join.

Parameters:: sock The socket to leave a multicast group

addr The address of the multicast group to leave

iface Address of the interface to use. If NULL is passed, the default multicast interface will be used. (OS Dependent)

source Source Address to accept transmissions from (non-NULL implies Source-Specific Multicast)

apr_status_t apr_mcast_loopback ( apr_socket_t * sock,

apr_byte_t opt

)

Toggle IP Multicast Loopback

Parameters:: sock The socket to set multicast loopback

opt 0=disable, 1=enable
