       pattern	Specifies the null-terminated pattern string
		 that can contain wildcard characters.

DESCRIPTION
       The XListFonts function returns an array of available font
       names (as controlled by the font search path; see
       XSetFontPath) that match the string you passed to the pat-
       tern argument.  The pattern string can contain any charac-
       ters, but each asterisk (*) is a wildcard for any number
       of characters, and each question mark (?) is a wildcard
       for a single character.	If the pattern string is not in
       the Host Portable Character Encoding, the result is imple-
       mentation-dependent.  Use of uppercase or lowercase does
       not matter.  Each returned string is null-terminated.  If
       the data returned by the server is in the Latin Portable
       Character Encoding, then the returned strings are in the
       Host Portable Character Encoding.  Otherwise, the result
       is implementation-dependent.  If there are no matching
       font names, XListFonts returns NULL.  The client should
       call XFreeFontNames when finished with the result to free
       the memory.

       The XFreeFontNames function frees the array and strings
       returned by XListFonts or XListFontsWithInfo.

       The XListFontsWithInfo function returns a list of font
       names that match the specified pattern and their associ-
       ated font information.  The list of names is limited to
       size specified by maxnames.  The information returned for
       each font is identical to what XLoadQueryFont would return
       except that the per-character metrics are not returned.
       The pattern string can contain any characters, but each
       asterisk (*) is a wildcard for any number of characters,
       and each question mark (?) is a wildcard for a single
       character.  If the pattern string is not in the Host
       Portable Character Encoding, the result is implementation-
       dependent.  Use of uppercase or lowercase does not matter.
       Each returned string is null-terminated. If the data
       returned by the server is in the Latin Portable Character
       Encoding, then the returned strings are in the Host
       Portable Character Encoding.  Otherwise, the result is
       implementation-dependent.  If there are no matching font
       names, XListFontsWithInfo returns NULL.

       To free only the allocated name array, the client should
       call XFreeFontNames.  To free both the name array and the
       font information array or to free just the font informa-
       tion array, the client should call XFreeFontInfo.

       The XFreeFontInfo function frees a font structure or an
       array of font structures and optionally an array of font
       names.  If NULL is passed for names, no font names are
       freed.  If a font structure for an open font (returned by
       XLoadQueryFont) is passed, the structure is freed, but the
