XmFontListGetNextFont(library call)			      XmFontListGetNextFont(library call)

       XmFontListGetNextFont -- A font list function that allows applications to access the fonts
       and character sets in a font list

       #include <Xm/Xm.h>
       Boolean XmFontListGetNextFont(
       XmFontContext context,
       XmStringCharSet *charset,
       XFontStruct **font);

       XmFontListGetNextFont accesses the character set and font for the next entry of	the  font
       list.  The  application	first uses the XmFontListInitFontContext routine to create a font
       list context.  The application then calls XmFontListGetNextFont repeatedly with	the  same
       context.  Each  succeeding call accesses the next element of the font list. When finished,
       the application calls XmFontListFreeFontContext to free the allocated font list context.

       This routine allocates memory for the character set string  that  must  be  freed  by  the
       application.   The  function allocates memory for charset.  The application is responsible
       for managing the allocated memory.  The application can recover the  allocated  memory  by
       calling XtFree.

       This  function  is  obsolete  and  exists  for compatibility with previous releases. It is
       replaced by XmFontListNextEntry.  If XmFontListGetNextFont is passed a context  that  con-
       tains  a  font  set entry, it will return the first font of the font set. The next call to
       the function will move to the next entry in the font list.

       context	 Specifies the font list context

       charset	 Specifies a pointer to a character set string; the routine returns the character
		 set for the current font list element

       font	 Specifies  a  pointer	to a pointer to a font structure; the routine returns the
		 font for the current font list element

       Returns True if the returned values are valid; otherwise, returns False.

       XmFontList(3) and XmFontListNextEntry(3).
