Application interface for the CAT decoder and the CAT generator.
>
Application interface for the CAT decoder and the CAT generator. New decoded CAT tables are sent by callback to the application.
bool dvbpsi_cat_attach | ( | dvbpsi_t * | p_dvbpsi, |
dvbpsi_cat_callback | pf_callback, | ||
void * | p_cb_data ) |
Creation and initialization of a CAT decoder. It will be attached to p_dvbpsi.
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 |
void dvbpsi_cat_delete | ( | dvbpsi_cat_t * | p_cat | ) |
Clean and free a dvbpsi_cat_t structure.
p_cat | pointer to the CAT structure |
dvbpsi_descriptor_t * dvbpsi_cat_descriptor_add | ( | dvbpsi_cat_t * | p_cat, |
uint8_t | i_tag, | ||
uint8_t | i_length, | ||
uint8_t * | p_data ) |
Add a descriptor in the CAT.
p_cat | pointer to the CAT structure |
i_tag | descriptor's tag |
i_length | descriptor's length |
p_data | descriptor's data |
void dvbpsi_cat_detach | ( | dvbpsi_t * | p_dvbpsi | ) |
Destroy a CAT decoder.
p_dvbpsi | handle to dvbpsi with attached decoder |
p_dvbpsi | handle holds the decoder pointer |
The handle isn't valid any more.

Initialize a user-allocated dvbpsi_cat_t structure.
p_cat | pointer to the CAT structure |
i_version | CAT version |
b_current_next | current next indicator |
References b_current_next, and i_version.
dvbpsi_cat_t * dvbpsi_cat_new | ( | uint8_t | i_version, |
bool | b_current_next ) |
