Programming :: Access A Function's Definition In "vim"?
Jun 23, 2010
I'm using ubuntu 9.04;Is there a complete library for C++ programming in ubuntu like "MSDN"?!hen using "Vim", I want to access a function's complete definition such as it's header file, library description and parameters, etc.Is it necessary to install something from repository to obtain such a documentation? And what would be the command to access a function's description in "vim"?
I have recently graduated from uni and during my time there I have developed an interest in HDL, specifically Verilog. As my current job doesn't lend itself to doing anything in verilog so I decided to keep myself sharp by designing a 32 bit processor that is similar to (but not the same as) the MIPS processor it will certainly be RISC. While starting work on it I have decided to start a blog detailing what I have done including the source file as I am entering my work into the wide world I think it needs a licence but I am not looking to make any money or even to derive any fame from what I'm doing. Like I said the main reason to do it is to keep me active in using HDLs.
I hope to gain from the blog suggestions for alternative(better) ways to do what I am doing, for people to use what I have done as an example of a medium sized project in verilog and to force me to have some form of documentation on my project. That's enough self publication to the question. Is the GPL (either version 2 or 3) applicable to work in HDL as it is not a traditional programming language but shares many of the same features? It certainly does not feel like I should use a CC license. I'm not sure this is the correct forum for this question but it seems most applicable.
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.
I looked on the net for such function or example and didin't find anything, thus after having made one i guess it would be legitimate to drop it to see what others thinks of it.

fit 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:
Code: I have a set of 100 numbers. I want to fit a 2-Dimensional function W(x,y) to these numbers.
As per my knowledge, one can use systemcall to call the driver functions for example using open, close... Now is there any way to call driver functions directly from application without using system call?
I have a question about calling an asm function from C....It doesn't work unless I create an asm variable to hold the value of the function in....Why?Here's the code that doesn't work...
asmfile.s - version one Code: .section .data mydata: .ascii "this is the message! .equ mylen, . - mydata
I want to use backtrace() function to debug a crash issue. I tried this sample code to see how backtrace works. backtrace() function always returns 0 with the below code. Is there any kernel configuration that needs to be set for proper working of backtrace?
#include <execinfo.h> #include <stdio.h> #include <stdlib.h> /* Obtain a backtrace and print it to stdout. */ void print_trace (void)
Can you offer me the code about fmod() in C. I want to know how this function work, i am very interested in it because i have no idea to implement it, i want to know... how to write the function... not 'how to use the function' can anyone post the source codes of this function here?
i have an open source application that was developed in C++ (it uses objects and namespaces all over the place). I also have another application that was developed in C. Now i am trying to insert the code made in C into C++ application, but when i do that , i get this error on compilation of the source code:
Code: error: 'mpi_init_vars' was not declared in this scope the function mpi_init_vars() is not part of object oriented programming and it doesn't belong to any scope, it was compiled into an object file and i am linking it with all objects of C++ application.
How can invoke the C function from C++ object oriented code?

I can find lots of tutorials in how to use if, then, else. However, how do I define a variable inside the function? SEE>> Code: for c in $ISO Also, am I using the 'test' command correctly( -/+ week as valid test)?
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.
Code: return ((unsigned int)(unsigned long)base & TBASE_DEFERRABLE_FLAG); What is the above function returning.I am not clear with definition of what is being returned in the above code.
i want to compile function c in java and compile library is success.. when i call the library in java and error is :
Exception in thread "main" java.lang.UnsatisfiedLinkError: no libfunc.so in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1689) at java.lang.Runtime.loadLibrary0(Runtime.java:823) at java.lang.System.loadLibrary(System.java:1028)
I tried to make a (very simple) function to put in my .bashrc file to make a local backup of a file, but when I call the function and try to use tab completion I get the following error: Code: cp: cannot stat `help': No such file or directory The function I added is as follows:
Code: function bk { cp -f --backup=numbered ${1} ${1}.bak
This is my file, named xxx.c. And there are two functions in it.

When I try to compile the whole project, I used -ffunction-sections,-fdata-sections to generate the .o files, use Wl,--gc-sections -Wl,--print-gc-sections to link to the exacutable file. gcc 4.3.2 ld 2.18 Debian 5 After the first time I compiled it, I got a list of Removed functions. But one second later, I rememberd that I forget to close the Compile Switch: Debug. Then I had to recompile it and got another list. Compare these two lists, I found that , bxx isn't on the second list. First I guess that bxx is a debug function but never used in debug mode, and it won't be compiled in release mode. I check the source and find that there was no compile switch for bxx. But it's caller function axx, is removed, both the debug switch is on and off. I try to compiled the project for several times , but the result is the same. I can't realized it , why? Is that the --gc-sections won't remove all the functions not used?
I'm doing a script to make some task but I would like to know how can I do the part to check the bu.log ? Cause if the files exists it will send me an email with the log, but when the file doesnt exist it will send a blank emal that why i would like to 'check the file' and if there isnt will end it.
#!/bin/sh x="$HOME/bu.log" if [ $x ]; then #if the file exists will do for file in *.log
[Code].....
How can I edit the funcion to check if there isnt an arq.log and close the script?
