|
|
*
|
|
* The Contiki DSC structure is used for describing programs. It
|
|
* includes a string describing the program, the name of the program
|
|
* file on disk (or a pointer to the programs initialization function
|
|
* for systems without disk support), a bitmap icon and a text version
|
|
* of the same icon.
|
|
*
|
|
* The DSC is saved into a file which can be loaded by programs such
|
|
* as the "Directory" application which reads all DSC files on disk
|
|
* and presents the icons and descriptions in a window.
