[lwip-users] Sockets - read() - without copying buffers

[ncoage]

Hi,

I'm using sockets API to receive some data from remote device. Is it possible 
to read incoming data without using function read(). I want to use directly 
internal buffer of the socket and want to get to know how many bytes are in the 
buffer. If its not possible - is there a method to check how many bytes I can 
read before reading them?

Best regards,
Gregory
