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 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 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 Por- table 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 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. SEE ALSO
