Debugger

[minix]

Hi,
I want to make a debugger for my application.
which also print line number and and file name.
and also accept variable argument list.
We don't need to pass line number and file name at the time of call.
So i have have to make this debugger by #define ?
Exmp --
//MyCpp.c
...
...
...
MyTrace("Hi");
int DD = 10 ;
MyTrace("Hi=%d" , DD);
...
...
...
//End Of File
=========O/P=============
Line 4 File MyCpp.c - Hi
Line 6 File MyCpp.c - Hi=10



Please help me out.
Thanks in advance.

See the following preprocessor directives:
__LINE__
__FILE__
__DATE__

I hope it will help you

i tried this ...
But its not solving my purpose :(
main problem is how to take variable type argument in #define

#define MyTrace(s) MyFunc(__FILE__,__LINE__,s)

[Denis]

#include <iotream>

#define LOG(a)\
std::cout << __LINE__ << '\t' << __FUNCTION__ << '\t' << a << '\n';\


void function(int a)
{
    LOG(a);
    ....//do something
}

But problem in my suggestion, you can pass only one argument
