 * Functional description
 *      Get address and length of string, converting the value to
 *      string, if necessary.  The caller must provide a sufficiently
 *      large temporary.  The address of the resultant string is returned
 *      by reference.  Get_string returns the length of the string (in bytes).
 *
 *      The text-type of the string is returned in ttype.
 *
 *      Note: If the descriptor is known to be a string type, the fourth
 *      argument (temp buffer) may be NULL.
 *
 *      If input (desc) is already a string, the output pointers
 *      point to the data of the same text_type.  If (desc) is not
 *      already a string, output pointers point to ttype_ascii.
