Remote Address from RSocket

[velund]

Hi.

I using RecvFrom method to read data from socket. As i understand TSockAddr &anAddr parameter should give me remote address... I receive the packet, but remote address is always empty.

code example: iSocket.RecvFrom(iBuffer, iRemoteAddr, iFlag, iStatus);

What can be the problem?

Thanks in advance.

This line in itself looks fine (assuming that everything is a member variable). Do you apply any special flags?
Otherwise, just to make sure: is this question about UDP or something else?

[velund]

Yes, I'm talking about UDP and iFlag is set to 0(Anyway couldn't find possible values for this parameter). I'm not connecting the socket to specific remote address, so i suppose i should get this address from RecvFrom... Is there any other way to get remote address?

How do you check the address you get? If you happen to use TInetAddr::Output, make sure that the buffer you pass is at least 32 (or 40?) characters long. Due to some bug the method checks for suitable descriptor-length for an IPv6 address, even if you are using IPv4.

RecvFrom takes TSockAddr and not TInetAddr. TSockAddr inherited from TBuf8, so i treat as a descriptor.

[velund]

Wow. In documentation RecvFrom receives only TSockAddr, but there is undocumented function that uses TInetAddr))) I tried it and it's worked)

Thanks for the tip.

I do not know what undocumented function you mean, but TInetAddr is a TSockAddr:

class TInetAddr : public TSockAddr;

Note that most (all?) descendants of TSockAddr also have Cast methods for "creating" specific address types from generic TSockAddr.

Ok,ok. My fault.
