Get a table of your driver's miscellaneous 2D drawing functions
int devg_get_miscfuncs (disp_adapter_t *ctx,
disp_draw_miscfuncs_t *fns,
int tabsize);
A 2D driver must provide an entry point called devg_get_miscfuncs().
The graphics framework calls it to get a table of your driver's
miscellaneous 2D drawing functions.
The arguments are:
- ctx
- A pointer to the
disp_adapter_t
structure that describes the graphics adapter.
- fns
- A pointer to a
disp_draw_miscfuncs_t
structure that your driver must fill with pointers to its miscellaneous
drawing functions.
- tabsize
- The size of the table, in bytes.
Use the
DISP_ADD_FUNC()
macro to add function pointers to the table.
It checks the tabsize argument and adds a function pointer only
if there's space for it in the table.
- 0
- Success.
- -1
- An error occurred.
