devg_get_vcapfuncs()

Get a table of your driver's video capture functions

Synopsis:

int devg_get_vcapfuncs (disp_adapter_t *ctx,
                       disp_vcapfuncs_t *funcs,
                       int tabsize);

Arguments:

ctx

A pointer to the disp_adapter_t structure that describes the graphics adapter.

funcs

A pointer to a disp_vcapfuncs_t structure that your driver must fill with pointers to its video capture functions.

tabsize

The size of the table, in bytes.

Description:

A driver that contains a video capture module must provide an entry point called devg_get_vcapfuncs(). The graphics framework calls it to get a table of your driver's video capture functions.

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.

---

This entry point is optional. A driver may not support video capture.

Returns:

0

Success.

-1

An error occurred.

Classification:
