Initialization and termination methods.

ACE_SOCK_Dgram_Bcast (void);

Default constructor.

ACE_SOCK_Dgram_Bcast (
    const ACE_Addr &local,
    int protocol_family = PF_INET,
    int protocol = 0,
    int reuse_addr = 0,
    const ASYS_TCHAR *host_name = 0
    );

~ACE_SOCK_Dgram_Bcast (void);

Default dtor.

Initiate a connectionless datagram broadcast endpoint.

int open (
    const ACE_Addr &local,
    int protocol_family = PF_INET,
    int protocol = 0,
    int reuse_addr = 0,
    const ASYS_TCHAR *host_name = 0
    );

Initiate a connectionless datagram broadcast endpoint.

int close (void);

Close up and release dynamically allocated resources.

ssize_t send (
    const void *buf,
    size_t n,
    u_short portnum,
    int flags = 0
    ) const;

Broadcast the datagram to every interface. Returns the average number of bytes sent.

ssize_t send (
    const iovec iov[],
    size_t n,
    u_short portnum,
    int flags = 0
    ) const;

Broadcast the iovec datagrams to every interface. Returns the average number of bytes sent.

ssize_t send (
    const void *buf,
    size_t n,
    const ACE_Addr &addr,
    int flags = 0
    ) const;

Broadcast an N byte datagram to ADDR (note that addr must be preassigned to the broadcast address of the subnet...).

ssize_t send (
    const iovec iov[],
    size_t n,
    const ACE_Addr &addr,
    int flags = 0
    ) const;

Broadcast an iovec of size n to addr as a datagram (note that addr must be preassigned to the broadcast address of the subnet...) */

void dump (void) const;

Dump the state of an object.

ACE_ALLOC_HOOK_DECLARE;

Declare the dynamic allocation hooks.
