[lwip-devel] [bug #46685] pcb->accepts_pending is not decreased

[Joel Cunningham]

Follow-up Comment #8, bug #46685 (project lwip):

Right, inside your accept callback, pcb is the new connection.  You'll need to
reference the listener pcb.  You could save this in a static global.  I would
imagine you're already storing your listener pcb somewhere that is not a
function scoped variable otherwise it would be leaking when your init function
goes out of scope

Or the listening pcb can be passed as the arg in your callback if you use
tcp_arg() to register the listener pcb

void ftpd_init (void)
{
    pcb = tcp_new();
    tcp_bind (pcb, IP_ADDR_ANY, 21);
    pcb = tcp_listen (pcb);
    tcp_arg(pcb, pcb);
    tcp_accept (pcb, ftpd_msgaccept);
}
