[lwip-users] Netconn API - receive check withput 1ms delay

[Marco Jakobs]

Dears,

 

to receive data from some connections I use the netconn receive timeout to have nonblocking reception.

 

The bad side is, that the minimum setting of "aTimeout" is 1, which is always a 1ms wait. Setting it to 0 disables the timeout.

 

Checking 20 connections for data means also a delay of 20ms here. I want to avoid this delay, so what I'm looking for is a "check if there is data in LwIP for this connection, if not – return".

 

Is there any way doing this in LwIP 1.4.0?

 

Thanks,

Marco
