Main lwIP docs are obsolete, and we have to update them. To do, to do...

lwip_socket_init() is "new" (26 February 2007). Ports need to be adapt. "See 
Change to port API: new call to lwip_socket_init()needed" thread in forum.

You have to call it in your module init sequence :

     #if LWIP_STATS
     stats_init      ();
     #endif /* STATS */
     #if (NO_SYS == 0)
     sys_init        ();
     #endif /* (NO_SYS == 0) */
     mem_init        ();
     memp_init       ();
     pbuf_init       ();
     etharp_init     ();
     netif_init      ();
     lwip_socket_init();

[lwip-users] lwip_socket_init where should this be called from?


I have just tried to start an Http server and it crashes with "OSSemPend failed 
at 215 in lwip/src/arch/sys_arch.c". Now looking throught the call stack I see

    [ 9] pc 0x107160, fp 0x153eb8, sys_arch_sem_wait()+0x9c
    [ 8] pc 0x107ea4, fp 0x153ed4, sys_sem_wait()+0x70
    [ 7] pc 0x13503c, fp 0x153ef0, alloc_socket()+0x30
    [ 6] pc 0x1359b8, fp 0x153f04, lwip_socket()+0x80
    [ 5] pc 0x124130, fp 0x153f34, ht_newServerSocket()+0x34
    [ 4] pc 0x1246ac, fp 0x153f90, httpd_start()+0x13c
    [ 3] pc 0x109468, fp 0x153fa4, _startHttp()+0x34
    [ 2] pc 0x109434, fp 0xdead701b, _startHttp()

So I decided to look a bit further and found the routine lwip_socket_init but I 
cannot find where its called so both sockets semaphores are not created?

Where should this be called from?
