Example
A simple example to parse yaml document.

def main(args: Array[String]): Unit = {

""".stripMargin
val input = toCString(inputStr).cast[Ptr[CUnsignedChar]]
val size = inputStr.length
// initialize parser
val parser = LibYaml.Parser()
if (yaml_parser_initialize(parser) == 0) {
stdio.fputs(toCString("failed to initialize parser"), stdio.stderr)
stdlib.exit(1)
}
// set input
yaml_parser_set_input_string(parser, input, size)
// parse document
val document = LibYaml.Document()

stdlib.exit(1)
}
stdio.printf(toCString("yaml version of document is: %d.%d\n"),
document.version_directive.major,
document.version_directive.minor)
// cleanup
yaml_document_delete(document)
yaml_parser_delete(parser)
}
