  26.           internal text buffer of a Text widget that is stored in a
  27.           wide character format. The function copies a specified
  28.           number of characters from a given start position in the
  29.           internal text buffer into a buffer provided by the
  30.           application. A NULL terminator is placed at the end of the
  31.           copied data.
  32.  
  33.           _w_i_d_g_e_t    Specifies the Text widget ID.
  34.  
  35.           _s_t_a_r_t     Specifies the beginning character position from
  36.                     which the data will be retrieved. This is an
  37.                     integer number of characters from the beginning of
  38.                     the text buffer. The first character position is 0
  39.                     (zero).
  40.

  43.  
  44.           _b_u_f_f_e_r__s_i_z_e
  45.                     Specifies the size of the supplied buffer as a
  46.                     number of wwwwcccchhhhaaaarrrr____ttttstorage locations. The minimum
  47.                     size is _n_u_m__c_h_a_r_s + 1.
  48.  
  49.           _b_u_f_f_e_r    Specifies the wide character buffer into which the
