tcp_recv() function

Sets the callback function that will be called when new data arrives. The callback function will be passed a NULL pbuf to indicate that the remote host has closed the connection. If the callback function returns ERR_OK or ERR_ABRT it must have freed the pbuf, otherwise it must not have freed it.

Syntax

from tcp.h:416

Implemented in tcp.c:2010

Arguments
