SYNTAX

       int XmbTextExtents(font_set, string, num_bytes,
       overall_ink_return, overall_logical_return)
             XFontSet font_set;
             char *string;
             int num_bytes;
             XRectangle *overall_ink_return;
             XRectangle *overall_logical_return;

       int XwcTextExtents(font_set, string, num_wchars,
       overall_ink_return, overall_logical_return)
             XFontSet font_set;
             wchar_t *string;
             int num_wchars;
             XRectangle *overall_ink_return;
             XRectangle *overall_logical_return;

       int Xutf8TextExtents(font_set, string, num_bytes,
       overall_ink_return, overall_logical_return)
             XFontSet font_set;
             char *string;
             int num_bytes;
             XRectangle *overall_ink_return;
             XRectangle *overall_logical_return;


ARGUMENTS

       font_set  Specifies the font set.

       num_bytes Specifies the number of bytes in the string
                 argument.

       num_wchars
                 Specifies the number of characters in the string
                 argument.

       overall_ink_return
                 Returns the overall ink dimensions.

       overall_logical_return
                 Returns the overall logical dimensions.

       string    Specifies the character string.


DESCRIPTION

       The XmbTextExtents, XwcTextExtents and Xutf8TextExtents
       functions set the components of the specified over-
       all_ink_return and overall_logical_return arguments to the
       overall bounding box of the string's image and a logical
       bounding box for spacing purposes, respectively.  They
       all_ink_return fields y = 0, x = 0, width = 1, and height
       = 1.

       If the overall_logical_return argument is non-NULL, it is
       set to the bounding box that provides minimum spacing to
       other graphical features for the string.  Other graphical
       features, for example, a border surrounding the text,
       should not intersect this rectangle.

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

       The function Xutf8TextExtents is an XFree86 extension
       introduced in XFree86 4.0.2. Its presence is indicated by
       the macro X_HAVE_UTF8_STRING.
