I have several libraries made by myself (a geometry library, a linked list library, etc). I want to make a header file to include them all in one lib.h. Could I do something like this:

#ifndef LIB_H_
#define LIB_H_

#include <stdio.h>
#include <stdlib.h>
#include <linkedlist.h>
#include <geometry.h>
....

#endif

Then I could just reference this one library and actually reference multiple libraries. Is this possible? If not, is there a way around it?
