## Detailed Description

## Function Documentation

int kate_decode_eventout | ( | kate_state * | k,
|  | kate_const kate_event ** | event
| ) |  |

Requests a pointer to the event decoded by the last packet, if there is one.

Parameters

  k | the kate_state to get the event from
  event | a pointer to where to place the pointer to the event, if any

Returns
  0 success, an event was returned
  1 success, but there was no event to return
  KATE_E_* error

int kate_decode_headerin | ( | kate_info * | ki,
|  | kate_comment * | kc,
|  | kate_packet * | kp
| ) |  |

Decodes a header packet, and updates the kate_info and kate_comment structures from the decoded data.

Parameters

  ki | the kate_info structure to update
  kc | the kate_comment structure to update
  kp | the packet to decode

Returns
  0 success
  1 success, and all headers have been decoded
  KATE_E_* error

int kate_decode_init | ( | kate_state * | k,
|  | kate_info * | ki
| ) |  |

Initializes a kate_state structure for decoding using the supplied kate_info structure. When done, the kate_state should be cleared using kate_clear.

Parameters

  k | the kate_state to initialize for decoding
  ki | the kate_info structure initialized from the decoded headers

Returns
  0 success
  KATE_E_* error

int kate_decode_is_idheader | ( | const kate_packet * | kp | ) |

Checks if a packet is a Kate ID header

Parameters

  kp | the packet to inspect

Returns
  0 the packet is not an ID header
  !=0 the packet is an ID header

int kate_decode_packetin | ( | kate_state * | k,
|  | kate_packet * | kp
| ) |  |

Decodes a data packet.

Parameters

  k | the kate_state to decode to
  kp | the packet to decode

Returns
  0 success
  1 success, and we're at end of stream
  KATE_E_* error

int kate_decode_seek | ( | kate_state * | k | ) |

Informs the Kate decoder that seeking has occured. This will cause the decoder to use any future repeat packets to recover data from past events which are still active, but which original packets were before the seek point, and therefore unavailable.

Parameters

  k | the kate_state for which a seek occured

Returns
  0 success
  KATE_E_* error
