Detailed Description
Application interface for the CAT decoder and the CAT generator.
>
- Author:
- Arnaud de Bossoreille de Ribou <bozo@via.ecp.fr> Application interface for the CAT decoder and the CAT generator. New decoded CAT tables are sent by callback to the application.
Function Documentation
Creation and initialization of a CAT decoder. It will be attached to p_dvbpsi.
- Parameters:
-
| p_dvbpsi | is a pointer to dvbpsi_t which holds a pointer to the decoder |
| pf_callback | function to call back on new CAT |
| p_cb_data | private data given in argument to the callback |
- Returns:
- true on success, false on failure
Clean and free a dvbpsi_cat_t structure.
- Parameters:
-
| p_cat | pointer to the CAT structure |
- Returns:
- nothing.
Add a descriptor in the CAT.
- Parameters:
-
| p_cat | pointer to the CAT structure |
| i_tag | descriptor's tag |
| i_length | descriptor's length |
| p_data | descriptor's data |
- Returns:
- a pointer to the added descriptor.
void dvbpsi_cat_detach |
( |
dvbpsi_t * |
p_dvbpsi |
) |
|
Destroy a CAT decoder.
- Parameters:
-
| p_dvbpsi | handle to dvbpsi with attached decoder |
| p_dvbpsi | handle holds the decoder pointer |
- Returns:
- nothing.
The handle isn't valid any more.
Clean a dvbpsi_cat_t structure.
- Parameters:
-
| p_cat | pointer to the CAT structure |
