ARGUMENTS
       array_size
		 Specifies the size of ink_array_return and logi‐
		 cal_array_return.  Note that the caller must pass in arrays
		 of this size.

       font_set	 Specifies the font set.

       ink_array_return
		 Returns the ink dimensions for each character.

       logical_array_return
		 Returns the logical dimensions for each character.

       num_bytes Specifies the number of bytes in the string argument.

       num_chars_return
		 Returns the number characters in the string argument.

       num_wchars
		 Specifies the number of characters in the string argument.

       overall_ink_return
		 Returns the overall ink extents of the entire string.

       overall_logical_return
		 Returns the overall logical extents of the entire string.

       string	 Specifies the character string.

DESCRIPTION
       The and return the text dimensions of each character of the specified
       text, using the fonts loaded for the specified font set.	 Each succes‐
       sive element of ink_array_return and logical_array_return is set to the
       successive character's drawn metrics, relative to the drawing origin of
       the string, one for each character in the supplied text string.	The
       number of elements of ink_array_return and logical_array_return that
       have been set is returned to num_chars_return.

       Each element of ink_array_return is set to the bounding box of the cor‐
       responding character's drawn foreground color.  Each element of logi‐
       cal_array_return is set to the bounding box which provides minimum
       spacing to other graphical features for the corresponding character.
       Other graphical features should not intersect any of the logi‐
       cal_array_return rectangles.

       Note that an represents the effective drawing dimensions of the charac‐
       ter, regardless of the number of font glyphs that are used to draw the
       character, or the direction in which the character is drawn.  If multi‐
       ple characters map to a single character glyph, the dimensions of all
       the of those characters are the same.

       When the has missing charsets, metrics for each unavailable character
       are taken from the default string returned by so that the metrics rep‐
       resent the text as it will actually be drawn.  The behavior for an
       invalid codepoint is undefined.

       If the array_size is too small for the number of characters in the sup‐
       plied text, the functions return zero and num_chars_return is set to
       the number of rectangles required.  Otherwise, the routines return a
       non-zero value.

       If the overall_ink_return or overall_logical_return argument is non-
       NULL, and return the maximum extent of the string's metrics to over‐
       all_ink_return or overall_logical_return, as returned by or
