[ECOS] is this a bug? (sendto socket call)

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

Hi All,

When I debugged deep into the various calls underneath 'sendto', I came across this section of code.  The call stack is something like this (not exact):

sendto -> sosend -> udp_send -> udp_output

In udp_output (udp_usrreq.c):
----------------- code -----------------------
    	if (addr) {
    		sin = (struct sockaddr_in *)addr;
    		laddr = inp->inp_laddr;
    		if (inp->inp_faddr.s_addr != INADDR_ANY) {         // <-------------------- ??
    			error = EISCONN;
    			goto release;
    		}
-------------------- end code -----------------------

The string inp_faddr is #defined to be inp_dependfaddr.inp46_foreign.ia46_addr4.

The structure for 'inp' is at the bottom of this email.   Anyway, in my debugger I see that inp_dependfaddr.inp46_foreign.ia46_addr4 is my desired remote address and  inp_dependladdr.inp46_foreign.ia46_addr4 is one of my local addresses.  Of course my remote address is not 0.0.0.0 (INADDR_ANY) and I get the 'is already connected' (EISCONN) error.  Does this make sense to anyone else?  It doesn't to me.  I can include any other information if this isn't enough.  I am using 'sendto' in a way that seems to work when I compile and run under Linux instead of eCos.

Thanks,
Rich
