How should a HTTP server (using sockets) detect that the client is no longer connected and abort processing? -

-

मैं एक मूल HTTP सर्वर को सी ++ में कार्यान्वित कर रहा हूं, boost :: asio।

I प्रत्येक अनुरोध को संसाधित करने के लिए, मैं अंशों में डेटा लिखता हूं, अस्तिष्क से। अगर किसी भी समय मुझे पता था कि क्लाइंट अब कनेक्ट नहीं था, तो मैं प्रसंस्करण को रद्द करना चाहता हूं, उदा।

मुझे लगता है कि यह पहले से कुछ बार पूछा गया है, उदाहरण के लिए:

लेकिन मैं उन्हें पढ़ रहा हूं, मुझे अभी भी यकीन नहीं है कि यहां एक अच्छा तरीका क्या है।

  • क्या मैं क्लाइंट सॉकेट से पढ़ने की कोशिश कर सकता हूं? (यहां तक ​​कि कि HTTP क्लाइंट दूसरे छोर पर किसी भी डेटा भेजने नहीं जा रहा है)
  • क्योंकि मैं asynchronously लिख रहा हूँ (boost :: asio :: async_write का उपयोग करके), मुझे नहीं लगता यदि ग्राहक अब नहीं है तो प्रतिक्रिया प्राप्त करने के लिए

यदि ग्राहक डिस्कनेक्ट हो जाता है, तो आपको चाहिए आपके एसिंक्रोनस लेखन को एक उपयुक्त त्रुटि कोड के साथ विफल हो। जब आपके पूर्णता वाले हैंडलर को एक त्रुटि के साथ लागू किया जाता है, तो उसके बाद गर्भपात की प्रक्रिया।

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
