SVector.H: void pop_back() throw (underflow_error); In my SVector.cpp file, should I also include the throw (underflow_error) part as well? void pop_back() throw (underflow_error) { // implementation } OR void pop_back() { // implementation } Thanks. ...
What I mean is, let's say you do an async_wait on an asio timer and bind the update to a function that takes a reference to a type T. Let's say you created the T initially on the stack before passing it to async_wait. At the end of that async_wait, it calls async_wait itself, renewing the timer over and over. Does that stack allocated ty...

I've stared at the Boost.Interprocess documentation for hours but still haven't been able to figure this out. In the doc, they have an example of creating a vector in shared memory like so: //Define an STL compatible allocator of ints that allocates from the managed_shared_memory. //This allocator will allow placing containers in the se...
Possible Duplicate: debugging finite state machine spell checker code I would love to have a debugged copy of the finite state machine code below. I tried debugging but could not, all the machine has to do is to spell check the word "and",an equivalent program using case is welcomed. #include<cstdlib> #include<stdio.h> #inclu...
I need start off with code because I am not sure what terminology to use. Lets say I have the following code: class Node { public: void Parse(rapidxml::xml_node<> *node) { for (rapidxml::xml_attribute<> *attr = node->first_attribute(); attr; attr = attr->next_attribute()) { std::stringstream converter;...
hello I have need to pack four signed bytes into 32-bit integral type. this is what I came up to: int32_t byte(int8_t c) { return (unsigned char)c; } int pack(char c0, char c1, ...) { return byte(c0) | byte(c1) << 8 | ...; } is this a good solution? Is it portable (not in communication sense)? is there a ready-made solution, perha...
Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separ...

I have a piece of mature geospatial software that has recently had areas rewritten to take better advantage of the multiple processors available in modern PCs. Specifically, display, GUI, spatial searching, and main processing have all been hived off to seperate threads. The software has a pretty sizeable GUI automation suite for funct...
How do I turn one file with lots of classes to many files with one class per file? (C\C++) So I have that file with such structure: Some includes and then lots of classes that sometimes call each other: #include <wchar.h> #include <stdlib.h> //... class PG_1 { //... } class PG_2 { //... } //...... class PG_N { //... } ...
How to convert AS3 ByteArray into wchar_t const* filename? So in my C code I have a function waiting for a file with void fun (wchar_t const* filename) how to send to that function my ByteArray? (Or, how should I re-write my function?) ...
It is probably something basic because I am just starting to learn LLVM.. The following creates a factorial function and tries to git and execute it (I know the generated func is correct because I was able to static compile and execute it). But I get segmentation fault upon execution of the function (in EE->runFunction(TheF, Args)) #i...
I try to create a very simple app using windows API. I've done some small apps in console. This is the first time I do with Win32 apps. I've searched and found a document from forgers which is recommended in this site. But I try to write very first line: #include <stdafx.h> #include <windows.h> int WINAPI WinMain(HINSTANCE hInstan...
Many windows APIs take a pointer to a buffer and a size element but the result needs to go into a c++ string. (I'm using windows unicode here so they are wstrings) Here is an example :- #include <iostream> #include <string> #include <vector> #include <windows.h> using namespace std; // This is the method I'm interested in improving ....
So I have some class starting with #include <wchar.h> #include <stdlib.h> ant there is that function wmain. What is it different from main function i usualy use in my C classes? ...
I'm trying to write a macro to make a specific usage of callbacks in C++ easier. All my callbacks are member functions and will take this as first argument and a second one whose type inherits from a common base class. The usual way to go is: register_callback(boost::bind(&my_class::member_function, this, _1)); I'd love to write: re...
