Programming :: Definitions For C Library Functions ?
Apr 24, 2010Where are the definitions for C library functions located? It was just recently that I realized that header files don't actually define any functions, they merely include their prototypes.
For instance, stdio.h includes the following line:
Code:
This just means that the definition of printf() is located in another file. What file? Is there some kind of default shared object file that is automatically included during compilation?
Programming :: C Library Or Some Functions To Read Proc Filesystem
Dec 6, 2010I have a requirement, to read the complete proc filesystem from the linux pc.. Does linux provide some functions to read the proc filesystem means the directories and files present in the filesystem.. in short I want to create a treeview of proc filesystem. and if a user selects the file in the proc.. I should show the contents in the respective file. So I want some library or functions to read the proc filesystem..

View 2 Replies View RelatedProgramming :: SDL Static Library - Shared Library ?
Apr 7, 2009I'm reading about shared, static, and dynamic libraries. What is SDL? Is it static, shared, or dynamic?
I always thought a library would be a lot of .h and .cpp files compiled separately into .o files and then if you compiled your own program you could use the -l parameter to link the library and it was all compiled together. Now I'm not so sure.
I don't even see any SDL .cpp files in my system anywhere. All I have are lots of SDL .h files in /usr/include/SDL and I don't really understand the code in them.
I'm making a wild guess here: SDL is a shared library. SDL itself is NOT compiled into my program, therefore SDL must be on any system my program tries to run on. When I compile and link SDL all it needs is the header files to know what SDL function and objects it can use. And then on every system it uses an already compiled SDL shared library thingy somewhere.
So... where is that part of SDL? All I can find are header files.
I'm thinking the advantage of shared libraries is that someone could say update SDL on their own system and take advantage of the new features without having to download new executables with the new version of SDL compiled into them for every program that uses SDL.
So if I'm making an editor and a game engine and they both use a lot of the same .cpp and .h files that I wrote and I'm tired of updating one and then the other and I need to turn them into a library, then a shared library might be kind of a silly solution. I could just make a static library. Right? Because it's not SDL. Nobody else is ever going to use this library.
Programming :: C++ Programming With Simple RTAI Functions Outputing Words?
Apr 11, 2011I need help as I am not proficient with Linux C++ Programming. There are two parts which I need to do in the coding provided below.
1. Produce the program so it can output the word "Hey there!" and wait two minute and print the word "See you later!".
2. Produce the program that will output the text "Cool" every 20 seconds by setting a periodic task.

Dec 14, 2008I want to do some experimentation with GUI programming. What mostly interests me is how the toolkits actually work (what are the drawing mechanisms, how it communicates with X, etc.) and how the window managers work. I know it's quite a lot but I don't plan on developing the next best DE/Toolkit/Window Manager, just to play with API, mostly to learn. It seems that there is a shortage of documentation on this topics, I'm trying to find anything for 2 days now with no result.

Jun 23, 2010I'm using ubuntu 9.04; I have a large project in windows that I want to "port" it in linux.
It uses IPC mechanism "Shared memory" and also "Critical Section" APIs in windows, but unfortunately I have no good reference to change these windows APIs to their equivalent in linux?
Is there a comprehensive documentation or reference for this issues? I mean a table containing the equivalent APIs or systemcalls in windows and linux! For example, what's an alternative for the "InitializeCriticalSection" API in linux? Or an alternative for "CRITICAL_SECTION" structure? Or even an alternative for "RegOpenKeyEx", although we don't have registry in linux!!
Programming :: Cannot Seem To Find Any Good Documentation On Role Of Flags
Mar 16, 2010I cannot seem to find any good documentation on the role of flags -Bdynamic and -Bstatic in g++. The man pages are not very helpful either.I found an example on the web:"gcc object1.o object2.o -Wl,-Bstatic -lapplejuice -Wl,-Bdynamic -lorangejuice -o binary".According to which -Bstatic instructs the linker to statically link
the applejuice library and to dynamically link the orangejuice library. If orangejuice uses the applejuice library anywhere however,the applejuice is also linked dynamically. Is it correct to assume that this is correct and describes the true functionality of those two flags in gcc? (ie: Bstatic and Bdynamic are used for mixing static and shared libraries during linking)Is it correct to assume that the same applies to g++ as well?

Programming :: Multithreading For Callback Functions
Jan 4, 2011Im implementing a chat application using Jabber/XMPP and gloox framework which should send and receive messages concurrently in Ubuntu Linux.
The problem faced is both the threads are created and pthread_join( ) is called for both.The iSend thread is scheduled first but gets suspended at cin. Once the recv( ) function is called, which runs in iRecv thread, the recv call back function handleMessage( ) is called. However the control never shifts back to the iSend thread which should call SendMessage( ) function.
Programming :: Nesting Switch Functions In C?
Apr 12, 2010I am trying to write a simple program in C that involves nesting switches. For example switch 1 offers an option to go to module 1 or 2 or quit. when I go to module 1 there is another switch function offering two or more choices.
I can select either module 1 or 2 at the start of the program and the selection text for, say, module 1 prints to screen but then exits without allowing a second selection to be entered.
I tried using free([first selection]) thinking that might do the trick but it doesn't.
Is it possible to next switches on after another in C?
Programming :: Macos Does Not Have Barrier Functions?
May 9, 2010The pthreads library on macos does not have barrier functions (pthread_barrier_t ....). Is there a way to get around this? I know I can do :

pthread_barrier_t ...
#else
my_barrier ...
#endif
But I would like to avoid this approach as there are a lot of places in my program where I would have to make this change. Can I perhaps rebuild the pthreads library on macos without affecting other apps ?

Programming :: Wrapping Around Functions With Different Return Types?
Feb 1, 2010I have functions which return different data like: int, char*, double...
I also have a list of datatypes (INTEGER, TEXT, REAL...) which can be returned.
I need to map a datatype with function, which purpose is to return it. Therefore, when I determine a datatype, I would like to call the required function without doing switch all the time.
My idea is to have an array of structs like this:
Code:
struct type_func_map
{
int type;
void (*func_wrapper_int)(void); //void (*func_wrapper_text)(void); void (*func_wrapper_real)(void);
};

Programming :: C++ - Calling Functions From Other Files And Headers?
Apr 11, 2011I feel like there should be a cleaner way of doing this. I have one file, for example "a.cpp", calling a function from another file, "b.cpp". Currently I have it set up so that header for "b", "b.h", has the declaration of its functions. And then I'm just including "b.h" in "a.cpp". Do I have to include the "b" header file in "a" to be able to call a function from "b"? Or is there a better way I could be doing this? Like doing something different at compile?

View 14 Replies View RelatedProgramming :: Calling Kernel Functions From Userspace?
Feb 5, 2010I'm trying to call some kernel functions from userspace, but I'm not sure if I'm doing it right. The functions control a pulse width modulator on an embedded platform. To pick one at random, the function:
Code:
struct pwm_device *pwm_request(int pwm_id, const char *label);
is defined in linux/pwm.h, and the implementation uses the macro EXPORT_SYMBOL(pwm_request), so I should be able to call this from user-space... right?
Anyway, I've got linux/pwm.h to #include in my source so the compiler knows what it's doing, but what do I link against? The only place in by kernel build tree where I can see a symbol pwm_request defined is in object files like vmlinux.o, built-in.o in the directory, etc. which I don't think I should be linking against.
