       int XFreeFontNames(char *list[]);

		 Returns the actual number of font names.

       count_return
		 Returns the actual number of matched font names.

       display	 Specifies the connection to the X server.

       info_return
		 Returns the font information.

       free_info Specifies the font information.


       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.


       pattern	 Specifies the null-terminated pattern string that can con-

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 XFree-
       FontNames.  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 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 font is not closed; use XUnloadFont to close the font.
