I'm trying to use "netlink" to get ip address of a Linux box. But the linux/types.h included from "linux/rtnetlink.h" introduced many conflicting type declarations with "sys/types.h".
#include <rtnetlink.h>
#include <sys/types.h>
#include <sys/socket.h>
int main (int argc, char *argv[])
{
return 0;
}
The program will demonstrate such type conflicts.
i have Ubuntu10.10 (kernel-2.6.35-22-generic) installed. struct stat StatBuff;
[Code]...
I have mounted a windows share folder on /mnt. When i gave any directory within /mnt/ to stat function it fails with errorno 75. perror shows "Value too large for defined data type". Example 1 is fail but Example 2 works fine.
I 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);
};

I'm creating a usb device driver that needs to be able to read from two different endpoints. I couldn't see any way of having two read functions in the driver, so I got round this by reading from one of the endpoints with read, and the other with ioctl.However this hasn't worked, the ioctl call from c returns -1. I added a printk command in the driver in the ioctl function, however looking at kern.log I can see that this function is never being called. Does anyone have any ideas as to what the problem called be, or a better method of being able to read from two different endpoints?

Afterwards I could find many remnants associated with the Anquet program which I've deleted. Except what remains is an association between my .gpx files with Anquet and that includes and any new gpx file I download. My interpretation is that during the install process an association has been created with the gpx file type and the Anquet map program. This is what I want to stop. If I download a .gpx file and look at it's properties I see- Type: GPX File -Anquet Mapsv06 (application/x-wine-extension-gpx) I found this file and it's contents-
/.local/share/mime/application/x-wine-extension-gpx.xml

Running "sudo update-mime-database /usr/share/mime" and rebooting didn't remove the association. How can I stop the Anquet name making as association with my gpx files?

It's for fast graphics. So I have a char array which I copy to another array. But I copy as either longs or ints, much faster. for example

I would like port 80 to have a small daemon running on it that detects HTTP traffic and sends a small redirect response, and any other traffic begins streaming data from my VPN daemon. I was wondering if this has already been made, or any kind of technology for detecting types of traffic and allowing you to run multiple types of servers on the same port.

What are the different types of API's in linux?How can we predict the kind of API we are using?And what are API layers related to?Are API's and system calls ,both are same?
View 5 Replies View RelatedI guess I'm just a noob, but I notice that some C libraries (and even some C++ ones) tend to redefine the basic types with their own naming convention.
For example, OpenGL redefines the basic types:
Code: from GL/gl.h
typedef unsigned int GLenum;
typedef unsigned char GLboolean;
typedef unsigned int GLbitfield;
typedef signed char GLbyte;
typedef short GLshort;
typedef int GLint;

i am searching for a table that gives info about the result of operations (+ , - , * , /) on data types
i mean if we * int by another int, the result should be assign in long so no overflow happens.
something like that.
like what will be the result of mult unsigned int by signed it , is there tables for such operations.
I decided to try making a programming language again after my last unsuccessful attempt, so now I figured how to write a good AST and it works great when the nodes are hard-coded into a test program. But to make a language out of it, I need a parser to build the tree according to an input file. I ran into a problem here:
YACC input file:
Code:
%{
#include "nodes/allnodes.h"
#include "Node.h"
int vars[26];
%}
%token SEMICOLON INTEGER VARIABLE IF WHILE DO OPAREN CPAREN OBRACE CBRACE
%right ASSIGN
%left NE
%left PLUS MINUS
%left TIMES DIVIDE
%% .....
As you might see, each nonterminal creates a Node* object and uses it as its value. The problem is that the literal tokens, however, don't return Node*'s and I don't know what to do. I would like to be able to convert literal tokens to nodes in the Lex file (which would avoid the problem), but the problem is with the assignment operator, which takes a Node* for the right-hand side and a variable name (not a Variable Node, because they just evaluate the the variable's value and you can't change the variable with them) for the left hand side.
I trying to write a UART(interfacing of serial devices) to linux machine but after I execute the following code to receive data I need to enter key (carriage return).... but I don't want to remove carriage return/enter key

View 4 Replies View Relatedi'm practicing in very basic c programs using the gcc compiler.I found that when i create two variables let's say
Code:
int a,b and Code: a=15;
b=3;
a=b;
b--;
then a equals 2.I thought that this isn't normal in C isn't it?I haven't had the time to read the gcc documentation yet...so i think it has something to do with my compiler's default settings.I use the
Code: gcc filename.c -o filename command to compile
Are all variables defined like pointers?
I converted my programming project over to autotools, which gives me a config.h file with all the cool definitions, like these ones:
Code:
/* Location of data files. */
#define DATADIR "/usr/local/share"
/* Define to the full name of this package. */
#define PACKAGE_NAME "lusus"
And naturally I think this is cool because then I can hardcore these into the binary. To my dismay, however, I discovered that the pre-processor does not do the text-substitution if the macro name is inside another quoted string.
Code:
// Prints out "/usr/local/share/lusus"
std::cout << DATADIR << "/" << PACKAGE_NAME << "
";
[code]....
This seems lame, because then this doesn't work:
Code:
CL_Image leaves_corner_tl(gc, "DATADIR/PACKAGE_NAME/img/leaves_corner_tl.png");
So, am I literally going to have to strcat DATADIR/PACKAGE with the other text every time I want to prefix DATADIR/PACKAGE_NAME onto another string?
I have a Red Hat 4.9 server running python 2.3.4. However I need some of the new functions so I downloaded and installed Python 2.7.1. I wanted to use the "set" function which was not in the earlier version.
/bin/python is 2.3.4
/usr/local/bin/python is 2.7.1
I have a script running 2.3.4 which calls the 2.7.1 script however it fails because it cannot find the "set" command here is an example
Script1
#!/bin/python
import Mytest
[code]....
The error message is :
NameError: global name 'set' is not defined
I've been reviewing some source code recently which contains many conditional compilation statements, and I found it hard to understand the code not knowing whether some macro is defined or not. Is there any way to test whether a macro is defined?
