This chapter explains what to and what not to keep in header files. In general, when we want to share data between multiple source files, we create a common header file and include it in each source file. For the following examples, we will use two source files and one common header file:
myheaderfile.h – shared header file
source.c – main source file
source2.c – second source file
A good practice is to guard the content of the myheaderfile.h file with the include guards/header guards:
#ifndef MYHEADERFILE_H
#define MYHEADERFILE_H
// code goes here
#endif
