FcFontSetSort - Add to a font set
#include <fontconfig/fontconfig.h>
FcFontSet * FcFontSetSort (FcConfig *config, FcFontSet **sets, intnsets, FcPattern *pattern, FcBool trim, FcCharSet **csp, FcResult *result);
Returns the list of fonts from sets sorted by closeness to
pattern. If trim is FcTrue, elements in the list which don't
include Unicode coverage not provided by earlier elements in the list are
elided. The union of Unicode coverage of all of the fonts is returned in
csp, if csp is not NULL. This function should be called only
after FcConfigSubstitute and FcDefaultSubstitute have been called for
p; otherwise the results will not be correct.
The returned FcFontSet references FcPattern structures which may
be shared by the return value from multiple FcFontSort calls, applications
cannot modify these patterns. Instead, they should be passed, along with
pattern to FcFontRenderPrepare which combines them into a
complete pattern.
The FcFontSet returned by FcFontSetSort is destroyed by calling
FcFontSetDestroy.
