XGetFontProperty()														XGetFontProperty()

Name
  XGetFontProperty - get a font property given its atom.

Synopsis
  Bool XGetFontProperty(font_struct, atom, value_return)
	XFontStruct *font_struct;
	Atom atom;
	unsigned long *value_return;

Arguments
  font_struct
	    Specifies the storage associated with the font.

  atom	    Specifies the atom associated with the property name you want returned.

  value_return
	    Returns the value of the font property.

Returns
  True if the atom was defined, else False.

Description
  XGetFontProperty()  returns  the value of the specified font property, given the atom for that property.  The function returns False if the
  atom was not defined, or True if was defined.

  There are a set of predefined atoms for font properties which can be found in <X11/Xatom.h>.	These atoms are listed and described in  Vol-
  ume One, Chapter 6, Drawing Graphics and Text. This set contains the standard properties associated with a font.  The predefined font prop-
  erties are likely but not guaranteed to be present for any given font.

  See Volume 0, Appendix M, Logical Font Description Conventions, for more information on font properties.
