How to check the buffer size of the underlying protocol.

Hello There:

I'm trying to send data through a socket using UDP, however when I try to send more than 1500 bytes, the EMSGSIZE error is generated.

How can I get and how I can modify this buffer size?

I have been using getsockopt() , setsockopt() and SO_SNDBUF with no success.

Any help would be very appreciated.

Gabriel.
