FcFontSort - Return list of matching fonts
#include <fontconfig/fontconfig.h>
FcFontSet * FcFontSort (FcConfig *config, FcPattern *p, FcBool trim, FcCharSet **csp, FcResult *result);
Returns the list of fonts sorted by closeness to p. 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
must not modify these patterns. Instead, they should be passed, along with
p to FcFontRenderPrepare which combines them into a complete
pattern.
The FcFontSet returned by FcFontSort is destroyed by calling
FcFontSetDestroy. If config is NULL, the current configuration is
used.
