RE: [ECOS] UDP on Rattler - newbie problem wtih bind

[Richard dot von dot Lehe at gd-ais dot com]

We've been doing joint development with Linux and eCos / Rattlers, too.  One thing I seem to remember is that in eCos, we had to specify the sin_len field of the sockaddr_in struct.  I'm not sure if that's what is causing your problem, but I think you need that.

Subject: [ECOS] UDP on Rattler - newbie problem wtih bind


I am trying to write a simple UDP-based server on a Rattler board (new
to ecos).

I get an error with bind() that it can't assign the requested address -
I am using INADDR_ANY - this code worked fine under linux.

The board is ping-able when the app is running.

Here is a portion of the code ...

Can anyone help me with this?

- Ian



#include <stdio.h>
#include <network.h>

...

static struct sockaddr_in local_addr;
static struct sockaddr_in client_address;
static int sd;

void comm_task( cyg_addrword_t ct_param)
{
int ret_val;
int rc;

unsigned int value;
int total_sent = 0;

int n = 0;

char buf[ MAX_UDP_SIZE ];
int reply_length;

unsigned char *parse_message( unsigned char *, 
                              unsigned int * );
int address_length;
int n_read, n_sent;
char *reply_ptr;

  printf( "Entering comm task\n" );

  memset( &local_addr, 0, sizeof(struct sockaddr_in) );

  local_addr.sin_family = AF_INET;
  local_addr.sin_port = htons( SERVER_PORT );
  local_addr.sin_addr.s_addr = htonl( INADDR_ANY ); 

  sd = socket( AF_INET, SOCK_DGRAM, 0);

  if( sd ) printf("socket retval = %d\n", sd );

  rc = bind( sd, 
             (struct sockaddr *) &local_addr, 
              sizeof(struct sockaddr_in) );
