global items used by the classes:
class CDatagramInterface:
CDatagramInterface
(ACSocketAddress* addr, INT32 sid): Stores the address and socket
ID. Assumes that a datagram socket with the ID sid exists and
is open. If addr is NULL, an assert fails.
CDatagramInterface
(ACSocketAddress *addr): Stores the address of the socket. If addr
is NULL, an assert fails.
EBool
ReceiveMessage (void *data, INT32 *size): Reads the data from the
socket (assumes that data points to a buffer of size *size).
Blocks according to the internal timeout. Modifies *size to reflect
the number of bytes read. Returns True if the receive operation was successful,
else False. If data or size is NULL, an assert fails.
EBool
SendMessage (void *data, INT32 size): Transmits the message over the
socket. Returns True if the operation was successful, else False. If data
is NULL, an assert fails.
class CDatagramServer:
Use this socket class to create a datagram socket. When the class is
deleted, the socket is closed and unlinked if necessary.
CDatagramServer
(ACSocketAddress *addr): Creates the datagram socket. If addr
is NULL, an assert fails.
virtual
~CDatagramServer (): Closes the socket and unlinks it if it has the
address family AF_UNIX.
class CDatagramClient:
Use this socket class to identify an existing datagram socket.
CDatagramClient
(ACSocketAddress *addr): Identifies the socket. If addr is
NULL, an assert fails.
