Programming :: Difference Between Init And Main Function In A Process
Jul 12, 2010I have a project in which many processes run. p1,p2,p3.
->There are some .so files are included in some process when needed example ppp.so in process p1 (when ppp is needed and will go like a plugin) but it has a init () function how a process includes a init() function ?
->process p1 has main function i.e main()
->so evry process has main() right ?

Programming :: Undefined Reference To 'main' Error In Crt1.o Function _start
Apr 13, 2011I've having problems with my Makefile.
I'm trying to create a program from 2 files - main.cpp that contains the main function, and modules.c that contains the definitions of the functions that are called in main(). modules.c only contain function definitions, no main function.
My Makefile is as follows:
Code:
I have included "modules.h", which contains all the function declarations, in my main.cpp.
When I try to make using this Makefile, I get the error
Code:
If I switch the order of modules.o and main.o in my $(TARGET) line, then I get errors that say "undefined reference to" the functions I have defined in modules.c, in main.cpp.

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?
May 18, 2010I 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.

May 18, 2010Here's my specs:
AMD Semprom 1.8Ghz
512 MB RAM
Nvidia TNT2 M64 @ 32 MB
I know it's old lol but probably better than the onboard graphics. The computer is a Compaq Presario sr1403wm. I checked proprietary drivers and there are none available. The graphics run smooth on the desktop and I don't have Compiz enabled. is the graphics card just too old for XBMC? Weird thing is, I also have the same problem in Ubuntu on my good desktop when it's connected to my TV. Just using a normal VGA cable. If I have it connected to my computer monitor using a DVI cable, there's no problem. The only thing I thought of was maybe the resolution was too high, but that made no difference with either computer. If this computer is too old for XBMC, what would be second best in line? MythTV? Doesn't need TV capabilities. Just to watch what's already on the computer. I just really like the XBMC interface and the fact that I can boot right into the interface and of course all the cool plugins and whatnot.

It then takes me to the login screen, and once I enter my password it just takes me back to the login.

Sep 16, 2010fit a surface i.e. W(x,y) using svdfit() provided by "Numerical Recipes in C". svdfit() is written for curve fitting and not for surface fitting.But one can use svdfit(), as claimed by authors of NR book, to do surface fitting. On page 680 of NR book, authors have given a hint on how to use svdfit() for fitting a surface. But I have not understood it.This link may be helpful (Chapter 15 th is relevant here.):[URL]This is my problem:
