sockets - Linux (uclinux 2.4.x) -


i have 1 doubt. using uclinux 2.4.x. in linux have own adapter code reading frames ingress port. have added debug log @ exact place reading frames word word , sure received number of frames transmitted peer. ( @ layer2 receiving frames).

from here onward invoking "netif_rx" send received framer upper layer (i.e network layer , transport layer).

doubt : observe there drop of packets @ (transport layer)udp protocol. how did confirm: added count check @ layer 1 , layer3(udp layer) , both counts not equal.

that means if receiving framer layer 1 when reaching udp in between somewhere drop happening.

so, 1 suggest problem be, how check if memory full or skb_alloc not happening more packets @ udp layer.

kindly suggest opinion, of great , support.

please let me know if need more information.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
