we have a function f with gets a string as below


void f( std::string str )
{
// body
}


is it safe to call this function with a const char* varialbe like below

The binary file used in program is a temporary file that is used during the
runtime of program. it does not even exist after the end of execution.
So I think the problems with portability can be...

I have an unkown object which is guaranteed to contain only POD's as
its member data.
Do the template functions below work correctly for saving and retrieval of its data from
a binary file?

I have found a solution to it in the below page under
section "Implementing Timers Using Signals"

we can use alarm() function call...

really need that, any tip is greatly appreciated
thanks!

could anyone tell me what function should I use for unix/linux?

Then what should i do for linux & windows cases?

Hi,
when using std::cin >> x; for getting a variable from user
the program is halted until the user inputs something. but
i want to have a time out (e.g. 10 seconds) which after
that the program...

Yes it compiles now!
Many thanks
I should go and learn some mpl!

excellent! I did not know we can do such thing with a few boost::mpl code!

I added the int main() below to the code and wanted to compile it but i get errors


int main(){
Stype::type ts1 =...

I think you are correct, map binary search is good, and I think it would be fastest if the series of
left/right comparisons become unrolled at compile time ( again metaprogram! )


in code it...

Thanks I did not know about Boost.Assignment
1- since the number of types T1,T2,... is limited (i'm sure it would be less than 10)
the map search algorithm becomes a little inefficient compared...

Hi, I have an enum in my program named Stype like below


enum Stype { T1, T2, T3 };


There is a template function compute which take two Stype as
template parameter

but it also works without setting the value of N like this


int main(){
int N;
int x[N];
}

Hi,
I am sure that the size of c style arrays must be known at compile tim
but the code below compiles. I am using g++ 4.2.4 and really confused!


int main(){
int N = 5;
int x[N];
x[2] = 3;...

My code is unstable currently and I want just to disable some part of it without removing it
maybe i decide to include that part again
#ifdef is a good solution but I was wondering if there is any...

Hi
I have a simple macro which I use when I want to disable part of my code


#define OBSOLETE_CODE(x)


But using this macro when you want to make many lines obsolete in not good
and looks...

but the signatures of foo::write_binary and global write_binary are different
so the compiler must be able to choose correct function
but it erros

Hi,
when I want to compile the below i get an error like
no matching function for call to ...

Many Thanks! it is a good solution
But is there better ones?
I was wondering if we can use a nested class and delegate things to it. since we can
use partial specialization for classes, something...

Regarding to my needs I am sure that the above interface is good for me.
And it is hard for me ( and maybe boring for you ) to tell why I need that
I need just that to work, is there any good...

I have a class which currently contains N vectors of int
and M vectors of double like below;

Thanks a lot! it worked

Hi,
Can anybody help me why this code does not compile (gcc 4.2.4)
what does the error "invalid operands of types ‘<unresolved overloaded function type>’ and ‘int’ to binary ‘operator<’" means?

Hello all,

I want to overload operator() of a class with a template function like below
//---------------------------
class A {
public:

template< int type >
void
operator()() {
