Precompiled Header Files

### Header Files

(ISO C, §6.10.2) The Carbide C preprocessor lets you nest up to 256 levels of #include directives.

You can use full path names in #include directives:

System | Directive
--- | ---
Windows | #include "c:\HD\Tools\my headers\macros.h"
UNIX | #include "/HD/Tools/my headers/macros.h"

The Carbide IDE lets you specify where the compiler looks for #include files through the Access Paths and Source Tree settings panels.

See also Prefix Files.

TIP If you are running the Carbide C compiler from the command line, you can specify where to find #include files with a command-line setting. For more information, see “Command-Line Tools”.
