Socket Programming - Receive

[srilaxmi@xxxxxxx]

Hi

I have a program written in ILE RPG (V4R2), that merely sends and receives
data structure to and from a PC via Socket.

For Example:

DbTLogonMsg       DS
D bMsgCode                       5U 0
D bMsgLen                           5U 0
D bChannelId                       5U 0
D bClientId                            5U 0
D bReserved                    10U 0
D bTimeStamp                 10U 0
D bErrorCode                    10U 0
D bErrorMsgLen                  5U 0
D bNoofDec                         1A
D bUserId                             5I 0

DStructure1       DS
D MsgCode1                       5U 0
D MsgLen1                           5U 0

DStructure2       DS
D MsgCode2                       5U 0
D MsgLen2                           5U 0
D ChannelId2                       5U 0
D ClientId2                            5U 0
D Reserved2                    10U 0
D TimeStamp2                 10U 0
D ErrorCode2                    10U 0



eval      rc = send(sock: %addr(bTLogonMsg):%size(bTLogonMsg):0)      <---
Sends that particular structure
eval      rc=recv(sock:%addr(bTLogonMsg):%size(bTLogonMsg):0)
<--- Receives the same structure


Example  2:
eval      rc = send(sock: %addr(bTLogonMsg):%size(bTLogonMsg):0)
eval      rc=recv(sock:%addr(buffer):%size(buffer):0)           <---
Different data structure (May be structure 1, structure 2 etc.)

where the var buffer should be able to receive different types of data
structure. How can I do that in RPG?
How can I point the buffer to a different structures and the first 2 fields
in all the structures are same.

When ever the socket receives something, trigger the event in rpg.Is anyone
have an idea about Socket event?

Pls help. TIA.

Rgds
