main_TcpNet

#include <rtl.h>

BOOL main_TcpNet (void);

The main_TcpNet is the main TcpNet function. It handles:

• protocol timeouts
• ARP address cache
• polling of the ethernet controller for received data.

When main_TcpNet receives data from the remote machine, it calls the appropriate TCPnet protocol functions to process the data and then passes the resulting data to the user application.

The main_TcpNet function is in the RL-TCPnet library. The prototype is defined in rtl.h.

note

• You must call main_TcpNet frequently. Otherwise the TCPnet system fails to run.

The main_TcpNet function returns __TRUE, if the TCPnet system is busy. If TCPnet system is idle, this function returns __FALSE.

The return value is used in event-driven operation mode of TCPnet in RTX environment.

init_TcpNet

#include <rtl.h>

void main (void) {

  init ();
  /* Initialize the TcpNet */
  init_TcpNet ();
  while (1);
    /* Run main TcpNet 'thread' */
    main_TcpNet ();
     ..
  }
}
