I am doing a web site program and what I need is to call a C program in the PHP cloud.Do u think it would be possible? The web site would get the user input from PHP UI and pass to the C program , the C program would process the function with the user input and output the a PHP page.

Why the thread stack size can not be changed after calling pthread_attr_setstacksize & pthread_create in a dynamic library? Detail: I write a file thread_factory.c and plan to build it and produce a dynamic library (libthread_factory.so) In the thread_factory.c , there is a routine
[Code]....
And after this, there is application, it will call fct_thread_create(STACK_SIZE_256KB), and then call pthread_attr_getstacksize(), but the stack size return always be a fixed value 0xa01000. (I tried this on Fedora12) But if I build the application source code with the file thread_factory.c directly, the stack size return is right as my expect. I checked the source code of glibc about the routine pthread_create() as below:

My calling application will accept only strings and interger. we are replacing RSA bsafe library to openssl. using RSA bsafe, we have generated the private and public key in BER format. Then convert the keys, BER format into ASCII format to send the calling function.

rsa = RSA_generate_key(1024, 3, NULL, NULL);

I read somewhere that you should not be reading config space to determine the irq value to pass as the first argument to request_irq(). What is the proper way to determine the value of the 'irq' argument before calling this function? Hope this is the correct forum. I don't see one for drivers.

View 2 Replies View RelatedI'd like to learn debugging techniques as much as to solve this particular problem. While trying to build yad 0.5.1:
Code:
yad-notification.o: In function `yad_notification_run':
/tmp/yad-0.5.1/src/notification.c:330: undefined reference to `gtk_status_icon_set_tooltip_text'
According to the source package's README file, "Yad depends on gtk+ only. Minimal gtk+ version is 2.12.0". I checked /var/log/packages and found gtk+2-2.14.7-i486-4 is installed.
Inspecting /tmp/yad-0.5.1/src/notification.c showed that gtk_status_icon_set_tooltip_text is a function. So it should be declared in the gtk+2-2.14.7 header files (or not?).
Checking:
Code:
c@CW8:/usr/include/gtk-2.0$ find . -name '*.h' -exec grep gtk_status_icon_set_tooltip_text {} ;
[no output]
Is this enough analysis to justify reporting an issue? Is there any more I can do before logging an issue?

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.
View 2 Replies View RelatedI'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.
How can we convert a dynamic library (filename.so) to a static library (filename.a) using gnu gcc . Can we get a static library form a dynamic library . I saw a few post in which the conversion form a static library to a dynamic library is mentioned but, unfortunately, not the other way.
