## Function Documentation

int yaml_stream_start_event_initialize | ( | yaml_event_t * | event,
|  | yaml_encoding_t | encoding
| ) |  |

Create the STREAM-START event.

Parameters:

  [out] | event | An empty event object.
  [in] | encoding | The stream encoding.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_stream_end_event_initialize | ( | yaml_event_t * | event | ) |

Create the STREAM-END event.

Parameters:

  [out] | event | An empty event object.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_document_start_event_initialize | ( | yaml_event_t * | event,
|  | yaml_version_directive_t * | version_directive,
|  | yaml_tag_directive_t * | tag_directives_start,
|  | yaml_tag_directive_t * | tag_directives_end,
|  | int | implicit
| ) |  |

Create the DOCUMENT-START event.

The implicit argument is considered as a stylistic parameter and may be ignored by the emitter.

Parameters:

  [out] | event | An empty event object.
  [in] | version_directive | The YAML directive value or `NULL`.
  [in] | tag_directives_start | The beginning of the TAG directives list.
  [in] | tag_directives_end | The end of the TAG directives list.
  [in] | implicit | If the document start indicator is implicit.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_document_end_event_initialize | ( | yaml_event_t * | event,
|  | int | implicit
| ) |  |

Create the DOCUMENT-END event.

The implicit argument is considered as a stylistic parameter and may be ignored by the emitter.

Parameters:

  [out] | event | An empty event object.
  [in] | implicit | If the document end indicator is implicit.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_alias_event_initialize | ( | yaml_event_t * | event,
|  | yaml_char_t * | anchor
| ) |  |

Create an ALIAS event.

Parameters:

  [out] | event | An empty event object.
  [in] | anchor | The anchor value.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_scalar_event_initialize | ( | yaml_event_t * | event,
|  | yaml_char_t * | anchor,
|  | yaml_char_t * | tag,
|  | yaml_char_t * | value,
|  | int | length,
|  | int | plain_implicit,
|  | int | quoted_implicit,
|  | yaml_scalar_style_t | style
| ) |  |

Create a SCALAR event.

The style argument may be ignored by the emitter.

Either the tag attribute or one of the plain_implicit and quoted_implicit flags must be set.

Parameters:

  [out] | event | An empty event object.
  [in] | anchor | The scalar anchor or `NULL`.
  [in] | tag | The scalar tag or `NULL`.
  [in] | value | The scalar value.
  [in] | length | The length of the scalar value.
  [in] | plain_implicit | If the tag may be omitted for the plain style.
  [in] | quoted_implicit | If the tag may be omitted for any non-plain style.
  [in] | style | The scalar style.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_sequence_start_event_initialize | ( | yaml_event_t * | event,

|  | yaml_char_t * | tag,
|  | int | implicit,
|  | yaml_sequence_style_t | style
| ) |  |

Create a SEQUENCE-START event.

The style argument may be ignored by the emitter.

Either the tag attribute or the implicit flag must be set.

Parameters:

  [out] | event | An empty event object.
  [in] | anchor | The sequence anchor or `NULL`.
  [in] | tag | The sequence tag or `NULL`.
  [in] | implicit | If the tag may be omitted.
  [in] | style | The sequence style.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_sequence_end_event_initialize | ( | yaml_event_t * | event | ) |

Create a SEQUENCE-END event.

Parameters:

  [out] | event | An empty event object.

Returns:
  `1` if the function succeeded, `0` on error.

int yaml_mapping_start_event_initialize | ( | yaml_event_t * | event,
|  | yaml_char_t * | anchor,
|  | yaml_char_t * | tag,
|  | int | implicit,
|  | yaml_mapping_style_t | style
| ) |  |

Create a MAPPING-START event.

The style argument may be ignored by the emitter.

Either the tag attribute or the implicit flag must be set.

Parameters:
