netconn_recved() — Update receive window


void netconn_recved (struct netconn *conn , u32_t length );


The application can call this function to notify the stack that it has processed the received data and is able to accept new data.


This function is primarily for use with sockets, and should be used with care. It can only be used when netconn_set_noautorecved(conn,1) has been used to disable the automatic receive window updating.
