devg_get_contextfuncs()

Get a table of your driver's context 2D drawing functions

Synopsis:

int devg_get_contextfuncs (
       disp_adapter_t *ctx,
       disp_draw_contextfuncs_t *fns,
       int tabsize);

Description:

A 2D driver must provide an entry point called devg_get_contextfuncs(). The graphics framework calls this function to get a table of your driver's context 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_contextfuncs_t structure that this function must fill with pointers to your driver's context 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.

Returns:

0

Success.

-1

An error occurred.

Classification:

Photon
