XListFonts(3)			XLIB FUNCTIONS			 XListFonts(3)

NAME
       XListFonts, XFreeFontNames, XListFontsWithInfo, XFreeFontInfo - obtain
       or free font names and information

SYNTAX
       char **XListFonts(Display *display, char *pattern, int maxnames, int
	      *actual_count_return);

       int XFreeFontNames(char *list[]);

       char **XListFontsWithInfo(Display *display, char *pattern, int max‐
	      names, int *count_return, XFontStruct **info_return);

       int XFreeFontInfo(char **names, XFontStruct *free_info, int
	      actual_count);

ARGUMENTS
       actual_count
		 Specifies the actual number of font names.

       actual_count_return
		 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 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 con‐
       tain 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 Por‐
       table 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.

       Note that XListFontsWithInfo is not thread-safe. If other threads make
       X requests on the same Display, then this function's behavior is unde‐
       fined.
