XCreateGlyphCursor()													      XCreateGlyphCursor()

Name
  XCreateGlyphCursor - create a cursor from font glyphs.

Synopsis
  Cursor XCreateGlyphCursor(display, source_font, mask_font, source_char, mask_char, foreground_color,	background_color)
 Display *display;
 Font source_font, mask_font;
 unsigned int source_char, mask_char;
 XColor *foreground_color;
 XColor *background_color;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  source_font
	    Specifies the font from which a character is to be used for the cursor.

  mask_font Specifies the mask font or None.

  source_char
	    Specifies the index into the cursor shape font.

  mask_char Specifies the index into the mask shape font.  Optional; specify 0 if not needed.

  foreground_color
	    Specifies the red, green, and blue (RGB) values for the foreground.

  background_color
	    Specifies the red, green, and blue (RGB) values for the background.

Returns
  The created cursor.

Description
  XCreateGlyphCursor()	is similar to XCreatePixmapCursor(), but the source and mask bitmaps are obtained from separate font characters, per-
  haps in separate fonts.  The mask font and character are optional.  If mask_char is not specified, all pixels of the source are displayed.

  The x offset for the hotspot of the created cursor is the left-bearing for the source character, and the y offset is the ascent, each  mea-
  sured from the upper-left corner of the bounding rectangle of the character.

  The  origins	of the source and mask (if it is defined) characters are positioned coincidently and define the hotspot.  The source and mask
  need not have the same bounding box metrics, and there is no restriction on the placement of the hotspot relative to the bounding boxes.

  Note that source_char and mask_char are of type unsigned int, not of type XChar2b.  For two-byte matrix fonts,  source_char  and  mask_char
  should be formed with the byte1 member in the most significant byte and the byte2 member in the least significant byte.

  You can free the fonts with XFreeFont() if they are no longer needed after creating the glyph cursor.

  For more information on fonts and cursors, see Volume One, Chapter 6, Drawing Graphics and Text.

Structures
     typedef struct {
	 unsigned long pixel;
	 unsigned short red, green, blue;
	 char flags;		/* DoRed, DoGreen, DoBlue */
	 char pad;
     } XColor;

Errors
  BadAlloc

  BadFont

  BadValue  source_char not defined in source_font.
	    mask_char not defined in mask_font (if mask_font defined).
