    Interface XmlInputProviderAlpha

    The input provider for Virtual IO.

    This interface defines four callbacks for reading the content of XML files. Each callback takes a 4-byte integer as the type of file descriptor.

    xmlRegisterInputProvider

    interface XmlInputProvider {
        close(fd: number): boolean;
        match(filename: string): boolean;
        open(filename: string): undefined | number;
        read(fd: number, buf: Uint8Array): number;
    }
