This directory is intended for project header files.
3+
4+
A header file is a file containing C declarations and macro definitions
5+
to be shared between several project source files. You request the use of a
6+
header file in your project source file (C, C++, etc) located in `src` folder
7+
by including it, with the C preprocessing directive `#include'.
8+
9+
```src/main.c
10+
11+
#include "header.h"
12+
13+
int main (void)
14+
{
15+
...
16+
}
17+
```
18+
19+
Including a header file produces the same results as copying the header file
20+
into each source file that needs it. Such copying would be time-consuming
21+
and error-prone. With a header file, the related declarations appear
22+
in only one place. If they need to be changed, they can be changed in one
23+
place, and programs that include the header file will automatically use the
24+
new version when next recompiled. The header file eliminates the labor of
25+
finding and changing all the copies as well as the risk that a failure to
26+
find one copy will result in inconsistencies within a program.
27+
28+
In C, the usual convention is to give header files names that end with `.h'.
29+
It is most portable to use only letters, digits, dashes, and underscores in
30+
header file names, and at most one dot.
31+
32+
Read more about using header files in official GCC documentation:
33+
34+
* Include Syntax
35+
* Include Operation
36+
* Once-Only Headers
37+
* Computed Includes
