Parser Definitions

typedef int yaml_read_handler_t(void *data, unsigned char *buffer, size_t size, size_t *size_read)

The prototype of a read handler.

The read handler is called when the parser needs to read more bytes from the source. The handler should write not more than size bytes to the buffer. The number of written bytes should be set to the length variable.

Parameters:

[ in,out ] data - A pointer to an application data specified by yaml_parser_set_input().

[ out ] buffer - The buffer to write the data from the source.

[ in ] size - The size of the buffer.

[ out ] size_read - The actual number of bytes read from the source.

Return
On success, the handler should return 1. If the handler failed, the returned value should be 0. On EOF, the handler should set the size_read to 0 and return 1.
yaml_simple_key_tThis structure holds information about a potential simple key.
yaml_parser_state_tThe states of the parser.
yaml_alias_data_tThis structure holds aliases data.
yaml_parser_tThe parser structure.
yaml_parser_initializeInitialize a parser.
yaml_parser_deleteDestroy a parser.
yaml_parser_set_input_stringSet a string input.
yaml_parser_set_input_fileSet a file input.
yaml_parser_set_inputSet a generic input handler.
yaml_parser_set_encodingSet the source encoding.
yaml_parser_scanScan the input stream and produce the next token.
yaml_parser_parseParse the input stream and produce the next parsing event.
yaml_parser_loadParse the input stream and produce the next YAML document.

Emitter Definitions

typedef int yaml_write_handler_t(void *data, unsigned char *buffer, size_t size)

The prototype of a write handler.

The write handler is called when the emitter needs to flush the accumulated characters to the output. The handler should write size bytes of the buffer to the output.

Parameters:

[ in,out ] data - A pointer to an application data specified by yaml_emitter_set_output().

[ in ] buffer - The buffer with bytes to be written.

[ in ] size - The size of the buffer.

Return
On success, the handler should return 1. If the handler failed, the returned value should be 0.

yaml_anchors_tThis is needed for C++
yaml_emitter_tThe emitter structure.
yaml_emitter_initializeInitialize an emitter.

yaml_emitter_set_canonicalSet if the output should be in the "canonical" format as in the YAML specification.
yaml_emitter_set_indentSet the indentation increment.
yaml_emitter_set_widthSet the preferred line width
yaml_emitter_set_unicodeSet if unescaped non-ASCII characters are allowed.
