Qt5 discard udp datagram without reading.

[JulienD]

Hello,

Context:
If a server receive two much data, its strategy is to discard the packets.

Question:
Is it possible to discard a UDP datagram and still get notified for the next ones?
The goal is to minimze the memory needed by an application to face offending packets.

I would like to avoid to have to read them (because I will discard them anyway). But this should only concern one -offending- udp datagram.

Alternatively, is reading 1 byte sufficient?

Thanks

Hi,

From QUdpSocket::readDatagram's documentation setting maxSize to 0 will discard the datagram.

Hope it helps
