void * dvbpsi_DuplicateDecodedDescriptor(void *p_decoded, ssize_t i_size)
Duplicate a decoded descriptor. The caller is responsible for releasing the associated memory.
dvbpsi_descriptor_t * dvbpsi_AddDescriptor(dvbpsi_descriptor_t *p_list, dvbpsi_descriptor_t *p_descriptor)
Add a descriptor to the end of descriptor list.
void dvbpsi_DeleteDescriptors(dvbpsi_descriptor_t *p_descriptor)
Destruction of a dvbpsi_descriptor_t structure together with the decoded descriptor,...
struct dvbpsi_descriptor_s dvbpsi_descriptor_t
dvbpsi_descriptor_t type definition.
bool dvbpsi_CanDecodeAsDescriptor(dvbpsi_descriptor_t *p_descriptor, const uint8_t i_tag)
Checks if descriptor tag matches.
bool dvbpsi_IsDescriptorDecoded(dvbpsi_descriptor_t *p_descriptor)
Checks if descriptor was already decoded.
uint8_t iso_639_language_code_t[3]
ISO639 three letter language codes.
