const char*和char**参数怎么传？

如：

extern NLS_API void NLS_internal_to_external(
    const char*  str_int,       /**< (I)  The input character data in Teamcenter internal encoding*/
    char**       str_ext        /**< (OF) The converted character data in platform encoding  */
    );

　传入的参数：

void translate2UTF2(char* GBKStr)  //add 2021/08/02
{
　　char* UTFStr = "\0";
    NLS_external_to_internal(GBKStr, &UTFStr);
