KwikNet Virtual File System

Compiling the VFS Data Files

The VFS Generator produces a set of one or more VFS Data Files which, collectively,

form your Virtual File System. These data files are C source files which must be

compiled to create your VFS object modules. If you wish, you can combine these VFS

object modules into a VFS library module using your object module librarian. Either the

VFS object modules or your VFS library module must be linked with your KwikNet

application.

Each VFS Data File is compiled in exactly the same manner as your own application

modules which use

KwikNet. The process is described in Chapter 3.4.

Note that the compilation depends on

KwikNet header file KN_VFS.H from subdirectory

TCPIP in the KwikNet installation directory. This header file will be copied to the Treck

installation directory

TRECK\INCLUDE when your KwikNet Library is created. Hence it is

always accessible for compilation along with all other

KwikNet header files.

Linking with the Virtual File System

Be sure to configure your KwikNet Library to include support for the Virtual File System.

To do so, check the Use VFS option on the File System property page as described in

Appendix C.2. If any of the files in your Virtual File System have been compressed, be

sure to check the option labeled Enable VFS Compression to ensure that these files will be

decompressed when accessed by your application.

If you are linking your Virtual File System as a set of one or more VFS object modules,

insert them prior to all libraries.

If you are linking your Virtual File System as one or more VFS library modules, insert

them following the KwikNet Library KNnnnIP.LIB. Note that library files may have the

extension .A or some other extension as dictated by the toolset which you are using.

Note

If symbol kvfs_primary is undefined, you have forgotten

to link the VFS data files which make up your Virtual File

System. If you have more than one VFS volume, you may

have linked the secondary volumes but the primary volume

has not been linked.
