Design a compiler like C

Hi :)
I'm developing a C like compiler and I whant to know, how it's work the include system... I mean, how the compiler works with the system include

The compiler read the entire code, and stores all includes found in one list and parser the includes, after finish the reading the current code?

// file main.c
#include <stdio.h> // store in one list

// continue the parse ...
int main()
{
    return 0;
}
// now, read the includes
// after finish the includes parse, gen code of sources

// just a sample
// file stdio.h
#include <types.h> // store in list
#include <bios.h>  // store in list

void printf(...)
{
}

void scanf(...)
{
}

Btw, I have developd an system ( only test ) to read the includes and, stop the parse, to read the include... ( it's a disgusting code, but, work... )
( link of sample )

Btw, What is the best way to read the includes... and work with includes files ??
