The Contiki program loader is an abstract interface for loading and starting programs.
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.
#define DSC | ( | dscname, | |
description, | |||
prgname, | |||
process, | |||
icon | |||
) | CLIF const struct dsc dscname = {description, prgname} |
Instantiating macro for the DSC structure.
dscname | The name of the C variable which is to contain the DSC. |
description | A one-line text describing the program. |
prgname | The name of the program on disk. |
initfunc | A pointer to the initialization function of the program. |
icon | A pointer to the CTK icon. |
#define LOADER_ERR_NOLOADER 9 |
#define LOADER_LOAD | ( | name, | |
arg | |||
) | LOADER_ERR_NOLOADER |
Load and execute a program.
This macro is used for loading and executing a program, and requires support from the architecture dependent code. The actual program loading is made by architecture specific functions.
name | The name of the program to be loaded. |
arg | A pointer argument that is passed to the program. |
