ARGUMENTS

       Specifies  the  actual  number  of  font names.	Returns the actual number of font names.  Returns the actual number of matched font names.
       Specifies the connection to the X server.  Returns the font information.  Specifies the font information.  Specifies the array  of  strings
       you  want to free.  Specifies the maximum number of names to be returned.  Specifies the list of font names.  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 num-
       ber of characters, and each question mark (?) is a wildcard for a single character. If the pattern string is not in the Host Portable Char-
       acter  Encoding, the result is implementation dependent. Use of uppercase or lowercase does not matter. Each returned string is null-termi-
       nated. 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,  XList-
       FontsWithInfo 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 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.
