File Inclusion

The preprocessor directive #include pulls in header files (extension .h) into the

source code. Do not rely on preprocessor to include source files (extension .c) —

see Projects for more information.

The syntax of

#include directive has two formats:

#include <

header_name

#include "

header_name

The preprocessor removes the #include line and replaces it with the entire text

of the header file at that point in the source code. The placement of the #include

can therefore influence the scope and duration of any identifiers in the included

file.

The difference between the two formats lies in the searching algorithm employed

in trying to locate the include file.

#include directive was used with the <

header_name

> version, the search is

made successively in each of the following locations, in this particular order:

1. mikroC installation folder > “include” folder,

2. your custom search paths.

The

header_name

" version specifies a user-supplied include file; mikroC will

look for the header file in following locations, in this particular order:

1. the project folder (folder which contains the project file

.ppc),

2. mikroC installation folder > “include” folder,

3. your custom search paths.

Explicit Path

If you place an explicit path in the

header_name, only that directory will be

searched. For example:

#include "C:\my_files\test.h"
