Software :: Reference List Of HTTP Header Info?
Apr 8, 2011I've been searching Google for a bit now, and either I'm too stupid or too tired to figure out the perfect search term for it.Im looking for a reference list of HTTP header info -- e.g, I have a program on Firefox that I can modify to send any header info i want "Safari, Mozilla, Internet Explorer" that sort of thing -- so a web site will believe Im using IE when in fact I am using Firefox.Does anyone have a reference of what the available "official" headers are? Also, a list of "OS header" responses would be nice, so I could fool something in believing I am a windows 3.1 machine.

Sep 18, 2010When is it good to use separate translation units and object files and link them into the main C program, and when is it good to include the header files in the main C program? I don't understand if most people include header files or if most people just link in object files and use their contents in the main program. It's sort of a simple question, but it's confusing to me and that's why I need help with it. I sort of don't understand the difference, or if there's really no difference other than the way the final result is achieved, which way is better or preferred, etc...
For example:
Code:
or:
Code:
Simple explanation of the difference? or which one is preferred or better? I've read a little on the ELF format... so is there no difference in the end result? It's just a matter of preference or necessity, and where the information is to begin with?
Programming :: Cannot Find Header Files To Use Kmalloc()
Jun 16, 2010I want to use kmalloc() to allocate contiguous memory on ram. But I can not seem to find the required header file(s) like linux/slab.h. I suppose I do not have the required library and I certainly do not know what and where to look.

Mar 10, 2010I have been a predominant Windows user for a long time but shifted to Ubuntu recently. I was just trying out a few basic C functions when i realized that the "conio.h" header file isn't included in the libraries and therefore i was unable to use the "clrscr()" function.
I downloaded a tarball which contained the necessary library and header files including conio.h. Once extracted, i specified the location and included in the program as " #include "path to the header file" ".
I still didn't call the "clrscr()" function, and it compiled successfully. Next i edited the program to call that function and it gave the following error...
How i can add new libraries in the future?
Programming :: Put Header Files For A Shared Library?
Feb 26, 2010I have written a simple library and ended up with a .so file. I have a header file from writing the code that describes how to use the functions in the source code I have written. I think this .h files needs to be available to other programs that access this code.
I have seen lots of tutorials on how to copy the .so file to the relevant directories and make links with the version number. What I can't find is where to put the header file so that any programs I write to use my new library can access the header.
Hope this makes sense. For example, I might use <stdio.h> normally, I will need to access <mylibrary.h> once mylibrary.so is loaded (as far as I understand!)
It's weird, I've been using C compilers for embedded processors over ten years now and never given a second thought to how libraries and headers work behind the scenes!

Programming :: Codeblocks Plugins And Header Files Location?
Jan 29, 2010I installed Codeblocks and build some programs, but I have two questions:1. Where are my header files placed, since I don't know where codeblocks is installed.

Plugins for Codeblocks can be installed, but when browse codeblocks's wiki I can't find download links neither developer pages

Mar 9, 2009I have created a simple test class - Mortgage, with the class declaration in the .h file and the class's methods defined in the .cpp file. (mortgage.h && mortgage.cpp, respectively) Straight up C++ 101 as far as I can tell. I instantiate the class in the main() function, which is defined in practice.cpp. Using Geany on Ubuntu, both the practice.o and mortgage.o files are created, but then I get a linker error: undefined reference to class::functionName
I get it for each function. If the mortgage.cpp file is foremost in the editor when I click "build", then I get the undefined reference to main() error, if practice.cpp is foremost (where the main() function is) then I get undefined reference to Mortgage::Mortgage(), and all the rest of the functions defined for that class. How do I get the linker to know where my object files are so it will link them in? Or is the problem somewhere else entirely?

General :: Cross Reference Matching Between Files?
Oct 18, 2009I'm trying to do something very basic in bash. It's a kind of cross-reference matching between 2 files. I have a file1.txt. It's like this:
Code:
item1
item3
item4
...
I Have a file2.txt. It's like this:
Code:
item1 "Properties of item1"
item2 "Properties of item2"
item3 "Properties of item3"
item4 "Properties of item4"
item5 "Properties of item5"
...
My goal is to print out the lines in file2 that contains lines present in file1. I do:
Code:
for i in $(cat file1.txt); do grep $i file2.txt; done but I get no output. Will someone please tell me where am I mistaking?
Programming :: Undefined Reference To Function While Linking
May 27, 2010I am trying to add some function to the c++ project (calling function) and the called function are in C. And i am getting error "undefined reference to "Hello(int,int)" " while linking. It is compiling correctly. It is linking to header file mention in the calling function. This header file has definition to the c - called function. Do you thinking having c files into C++ project will be a problem? Should I remove <stdio.h> in c files?

Ubuntu :: How To Use Formulas In OneOffice.org Spreadsheet
Dec 29, 2010I'm trying to create a simple times table on OpenOffice.org Spreadsheet
I'm trying to use the "$" in the top tab (input line) i.e.
Quote:
=A3*$B2$
Quote:
=A3*$B3$
[Code].....
To make the question clearer. When I used to use Microsoft Excel in Windows I would do just as I said in the above and I would be able to construct simple multiplication tables to more bigger/harder to memorize kind of type. And that would be by dragging the rectangle from it's bottom-right corner
Screenshot-5.jpg

So my question is what's the alternative OpenOffice.org Spreadsheet symbol for the "$" symbol used in the formula bar in Microsoft Excel?
