ARGUMENTS
       actualcount
                 Specifies the actual number of matched font names returned
                 by XListFontsWithInfo.

       actualcountreturn
                 Returns the actual number of font names.

       countreturn
                 Returns the actual number of matched font names.

       display   Specifies the connection to the X server.

       inforeturn
                 Returns the font information.

       freeinfo Specifies the font information returned by
                 XListFontsWithInfo.

       list      Specifies the array of strings you want to free.

       maxnames  Specifies the maximum number of names to be returned.

       names     Specifies the list of font names returned by
                 XListFontsWithInfo.

       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 pattern argument.  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,
       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 associated 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 information array, the client should
       call XFreeFontInfo.

       The XFreeFontInfo function frees the the font information array.  To
       free an XFontStruct structure without closing the font, call
       XFreeFontInfo with the names argument specified as NULL.
