 * Description:
 *       These routines write a chtype or cchar_t string directly into
 *       the window structure, starting at the current or specified
 *       position. The four routines with n as the last argument copy at
 *       most n elements, but no more than will fit on the line. If n =
 *       -1 then the whole string is copied, up to the maximum number
 *       that will fit on the line.
 *
 *       The cursor position is not advanced. These routines do not check
 *       for newline or other special characters, nor does any line
 *       wrapping occur.
 *
 * Return Value:
 *       All functions return OK or ERR.
 *
