[lwip-users] question of send proccess

[Oscar F]

Hello everybody

I´m using FreeRTOS with lwip in AVR32.  In my case i have to send an ACK message by TCP connection. I´m using the function send, but i have a quetion 
when i call this function, my program wait for send all packet or the function send isn´t blocking?

This task 
/* Create the task that handles the MACB input packets. */
  sys_thread_new( "ETHINT", ethernetif_input, netif, netifINTERFACE_TASK_STACK_SIZE,
                  netifINTERFACE_TASK_PRIORITY );

is it controlling only the recepction, or the transsmision too?


This other task
   result = xTaskCreate( thread, ( signed portCHAR * ) "lwIP", lwipINTERFACE_STACK_SIZE, arg, prio, &CreatedTask );
what things is it doing this task in the process to send a data with the function send(...)?

Thanks in advance
Regards
Oscar
