You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: writerc.go
    path of file: ./repos/lazydocker/vendor/github.com/jesseduffield/yaml
    
    the code of the file until where you have to start completion: package yaml

// Set the writer error and return false.
func yaml_emitter_set_writer_error(emitter *yaml_emitter_t, problem string) bool {
	emitter.error = yaml_WRITER_ERROR
	emitter.problem = problem
	return false
}

// Flush the output buffer.
func yaml_emitter_flush(emitter *yaml_emitter_t) bool {
	if emitter.write_handler == nil {
		panic("write handler not set")
	}

	// Ch
    
func yaml_emitter_flush(emitter *yaml_emitter_t) bool {
	if emitter.write_handler == nil {
		panic("write handler not set")
	}

	// Check if the buffer is empty.
	if emitter.buffer_pos == 0 {
		return true
	}

	if err := emitter.write_handler(emitter, emitter.buffer[:emitter.buffer_pos]); err != nil {
		return yaml_emitter_set_writer_error(emitter, "write error: "+err.Error())
	}
	emitter.buffer_pos = 0
	return true
}
