/*
* gdata_parser_boolean_from_json_member:
* @reader: #JsonReader cursor object to read the JSON node from
* @member_name: the name of the JSON object member to parse
* @options: a bitwise combination of parsing options from #GDataParserOptions, or %P_NONE
* @output: (out caller-allocates): the return location for the parsed boolean value
* @success: (out caller-allocates): the return location for a value which is %TRUE if the boolean was parsed successfully, %FALSE if an error was encountered,
* and undefined if @member_name was not found in the current object in @reader
* @error: (allow-none): a #GError, or %NULL
*
* Gets the boolean value of the @member_name member of the current object in the #JsonReader, subject to various checks specified by @options.
*
* If no member matching @member_name can be found in the current @reader JSON object, %FALSE will be returned, @error will be unset and @success will be unset. @output will be undefined.
*
* If @member_name is found but one of the checks specified by @options fails, %TRUE will be returned, @error will be set to a
* %GDATA_SERVICE_ERROR_PROTOCOL_ERROR error and @success will be set to %FALSE. @output will be undefined.
*
* If @member_name is found and all of the checks specified by @options pass, %TRUE will be returned, @error will be unset and
* @success will be set to %TRUE. @output will be set to the parsed value.
*
* The reason for returning the success of the parsing in @success is so that calls to gdata_parser_boolean_from_json_node() can be chained
* together in a large "or" statement based on their return values, for the purposes of determining whether any of the calls matched
* a given JSON node. If any of the calls to gdata_parser_boolean_from_json_node() return %TRUE, the value of @success can be examined.
*
* Return value: %TRUE if @member_name was found, %FALSE otherwise
*
* Since: 0.15.0
