I 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;
[Code].....
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 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.

View 5 Replies View Relatedi 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 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);
};
[Code].....
#define TRIP 6
#include <stdio.h>
char error_area(char area_code, char S, char M, char L,char N,char P, char K, char R, char
[code].....
The first line of this struct:
Code:
struct custom_int {
typedef int big_int;
[code]...
can anyone provide me with the path where i can find the library files. stdio.h, sys/types.h.......
View 4 Replies View RelatedI've done some hunting on this and other forums as well as my own system and have come up dry. I have a SLES10 box where root is using the Korn shell as the default. There was a lot of system configuration done by the vendor of the app that sits on this box and one of the "features" is that Ctrl+C no longer sends a SIGINT. I just get "^C" when I try. Needless to say, I'd like to redefine this so that I can kill commands/scripts without the need to manually whack the PID. Where is the Ctrl+C defined and what steps do I take to redefine it to its default behavior?

Im running ubuntu 9.04 remotley via ssh, using putty on a windows computer to control it. I want to redefine one key (I have a swedish keyboard where I have to press AltGr+key to get a tilde sign, would be better if I could get the tilde without AltGr modifier).
I read about xmodmap and xev. Using them I succesfully redefined the key for x-programs. For example if I start firefox over ssh and press the key I get the correct key. But in the terminal session the changes does not take effect. Which is probably logical since xmodmap does only work on the x-server. But how do I redefine the keys for terminal use?
I'm using Grsync and I want to be able to plug in any drive into my laptop and run rsync on it to back up all the user documents on there to another external hdd and to exclude everything else. Working on the principle that user documents don't always appear where we'd expect I want rsync to look through the whole drive and filter what it backs up by file type. I am only having partial success, however.
I am using the 'filter' option in the 'additional options' box. I am using the command
Code:
filter='merge /home/tim/Desktop/filter'
and I am attaching the filter file I have written. (I have added the .txt extention to upload it).
I have tested this script on my home folder and here's what's going wrong. Rsync will copy the entire directory structure regardless of whether there are any files to be copied over in those directories. I am also getting only some file types getting included and not others. .odt and .ods files are copied, for instance, but not .doc or .rtf.

using PHP. However I would like to have it very basic and simple to install. (not database SQL, nor complicated things, ...) so that I get a prompt page with login and password to access the SSH-internet, and then can SSH the linux box over SSL and regular port 80 like they do. passwd would be in a txt file or whatever. You use index.htm and no one can scroll the tree of the directory. Would have someone already embedded php code for that?

Where "surface" could be several different types, which will be set during execution. Hope this is clear enough. I have tried using templates but am getting "data member cannot be a member template". Either I have incorrect syntax, or am not implementing it right. another solution would have one class containing definitions of all possible shapes, But this would take up extra memory. Other solutions I thought of seem too round-about, and seems there is a simpler solution that I have overlooked.
