Xlib Programming Manual: XListFontsWithInfo

XListFontsWithInfo

Syntax

char **XListFontsWithInfo(display, pattern, maxnames, count_return, info_return)
      Display *display;
      char *pattern;
      int maxnames;
      int *count_return;
      XFontStruct **info_return;

Arguments

display Specifies the connection to the X server.
pattern Specifies the null-terminated pattern string that can contain wildcard characters.
maxnames Specifies the maximum number of names to be returned.
count_return Returns the actual number of matched font names.
info_return Returns the font information.

Description

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().
