Source Code Structure

RTFiles-32 comes with six header files in directory Include:

Filename	Depends on	Comments
Rtfcfg.h	-	Defines basic data types and compile time options.
Rtfiles.prv	-	Declares RTFiles-32 internal functions and data structures. The portable file system as well as the drivers need this file.
Rtfiles.drv	-	Declares data structures required by the device drivers.
Rtfiles.h	Rtfcfg.h	Defines the RTFiles-32 API. Applications need to include this file.
Rtfsys.h	Rtfiles.h	Defines the RTFiles-32 system driver API.
Rtfex.h	Rtfiles.h	API of the C exception handling library. The core file system and some of the drivers use exceptions internally.

The file system sources are located in directory Source\Rtf32:
