USAGE
EXAMPLE
The generated C file also contains two function which can be called to register or
unregister all of the packed files and directories; they are mounted as a filesystem using
memDevCreateDir(), and unmounted using memDevDelete( ). An include file is also
generated, containing a declaration of this function.
This utility is invoked as:
memdrvbuild [ -o filebase ] [ -m mount ] directory
where:
-o filebase
The base name for the generated .c and .h files. Defaults to the name of the source
directory.
-m mount
The name (“mount point”) under which directory will be mounted on the target.
Defaults to the name of the source directory.
directory
The source directory containing the files to be packed into a memDrv filesystem.
The output .c file contains two function, called memDrvAddFilesmount( ) and
memDrvDeleteFilesmount(), where mount is the argument to the -d option, with nonalpha
characters converted to _. This first function mounts the packed files using
memDevCreate(). The second function unmounts the packed files using memDevDelete( ).
The .h file contains a declaration of those functions.
Each file will be mounted with the name mount/file, where file is the pathname of the file
below the indicated source directory.
Given a directory docs, containing a number of files:
memdrvbuild -m /mem -o memFiles docs
will produce two files, memFiles.c and memFiles.h. memFiles.c will contain the data for
the packed files, plus two functions:
STATUS memDrvAddFiles_mem (void);
STATUS memDrvDeleteFiles_mem (void);
When called, the first function will mount all of the contained files in the filesystem under
/mem. For example, the file docs/fred.html would be mounted as /mem/fred.html. The
second function will unmount all of the contained files in the filesystem under /mem.
