      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.
