43 * Unlike the standard strtoul(), this function has an interface
44 * that makes it better suited for protocol parsers. It's also
45 * much simpler and smaller than a full featured strtoul().
47 * \param first Pointer to first byte of input range (STL-style).
48 * \param last Pointer to end of input range (STL-style).
49 * Pass NULL to parse up to the first \\0.
50 * \param val Pointer to converted value.
52 * \return true for success, false for failure.
