<p>Description: Create an <a class="el" href="class_o_n___length_value.html">ON_LengthValue</a> by parsing a string. Parameters: parse_settings - [in] Pass <a class="el" href="class_o_n___parse_settings.html">ON_ParseSettings(context_length_unit_system,context_angle_unit_system,context_locale_id)</a> string - [in] null terminated string to parse. string_count - [in] string[] and string_count specify the string to parse. If string_count &gt;= 0, it specifies the maximum number of elements in string[] that may be parsed. If string_count = -1, then the string must contain a character that terminates length parsing. string_end - [out] If string_end is not nullptr, then *string_end points to the first element in the string that was not parsed. Returns: If the string is valid, the exact length value is returned. If the string is not valid or parsing ends before the string's null terminator, the <a class="el" href="class_o_n___length_value.html#a224be66420350e567f9cb645181558f8">ON_LengthValue::Unset</a> is returned. Remarks: If the entire string is not parsed, that is an error condition. Use <a class="el" href="class_o_n___length_value.html#ae1cb03ea30a20d69a03948c423948304">CreateFromSubString()</a> to permit parsing a portion of the string. </p>
