How do you Load a Header file?

I want to load a header file I made.......but i dont know how to call it or interpret it in anyway. for example.

#include <windows.h> //windows main files
#include <gl/gl.h> //OpenGL main file
#include <gl/glu.h> //OpenGL library kit main files
#include "Loader.h" //Loads Bitmap Files

thats the problem I dont know how to call it so it can be used to load the Bitmap files and convert it to textures.
:(

#include "Loader.h"

This statement is correct and any code that you wrote within that header file will be entered into your code during the preprocessor stage.

But, if that's not what you mean, then please explain a little more clearly - I'm a tad confused.

Like ok when you create a Header file and you want it to be compiled at a certain Line of the codes. for example.

01 printf(" Hellow world ");
05 ......right here you want to caLL the header file
10getchar();

So do you get what Im saying now :p

You can't call the header file, you include it.
If you mean call a function thats defined in your header file then you can call that function wherever.

Code:

---

#include "Loader.h"

int main( void )
{
    // do stuff

    Load_Bitmap();  // function defined in Loader.h

    // do more stuff

    return 0;
}

I'm still lost. Ugh.

Let's say your header file has this inside of it.

myHeader.h
#define maxline 1024
#define minline 10

myProg1.c
#include "myHeader.h"
... code ...

myProg.c is now (after the include):
#define maxline 1024
#define minline 10
... code ...

All that the include statement does is text insertion. If you want a certain function to be called at some arbitrary place in your code then write a seperate file (myOtherFile.c) with all of your functions and include it.

#include "myOtherFile.c"

Header file generally contain only constants, ifdef statments, etc..

Oh I understand now, your saying I can call a funtion thats in the Loader.h file. At any time I want to in the code.:D
Ok so now its making sense to me thanks man. ;)

you must compile your functions into object file, then put them into library, then make a header file that is function declarations
then you can say include <bitmap.h> assuming you save your
objects and header file with the standard c headers altogether
