httpd bug

[Gerster Jochen-B01096]

Hi
 
here is a patch for the httpd network monitor handler
using ecos on target board with less memory I can happen that 
getifaddrs(..) returns with NULL = out of memory but this isn't
checked until now so ....
 
 
 static cyg_bool cyg_monitor_network( FILE * client, char *filename,
                                      char *formdata, void *arg )
 {
     struct ifaddrs *iflist, *ifp;
 
-    getifaddrs(&iflist);
+    if(getifaddrs(&iflist)!=0)
+  return 0;
     
     html_begin(client);
 
     html_head(client,"eCos Network Monitor", "");
 
 
Jochen
