compiler construction - What is Symbol Resolution? -

-

This is one of the things that talks about every conversation but nobody defines ... It does not seem to have any information on this topic, what is the symbol resolution? I have found that the best thing is:

Is your program compiled, what is there to do with it?

OK, now when you refer to the NM of Unix, I can specify the symbol resolution Can i

Executable files can be done in the context of those entities which are not defined in themselves. For example, variables or processes on shared libraries Those institutions are identified by external symbols. Executables can also have internal symbols that can be referred to by external files - as is also in case of libraries.

The symbolic resolution, in this context, once the program is loaded into memory, will tell the appropriate address to all external institutions, which refers to it, which means that every situation in the weighted program is to change, where A reference was made to the outer symbol.

These addresses will depend on whether the code with external symbols has been loaded into memory.

In Unix, the default compilation mode for programs is to use the System Shared Library before adding all the required components in the executable. For example, by passing the -static flag if you want to compile it rather than temporarily compiled contexts, compile the program containing GCC .

See "Shared Library" for more information.

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

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...
