FcToLower – convert upper case ASCII to lower case Synopsis#include <fontconfig/fontconfig.h> FcChar8 FcToLower (FcChar8c); DescriptionThis macro converts upper case ASCII c to the equivalent lower case letter.
FcStrStrIgnoreCase – locate UTF-8 substring ignoring ASCII case Synopsis#include <fontconfig/fontconfig.h> FcChar8 * FcStrStrIgnoreCase (const FcChar8 *s1, const FcChar8 *s2); DescriptionReturns the location of s2 in s1, ignoring case. Returns NULL if s2 is not present in s1. This test is case-insensitive for all proper UTF-8 encoded strings.
FcStrStr – locate UTF-8 substring Synopsis#include <fontconfig/fontconfig.h> FcChar8 * FcStrStr (const FcChar8 *s1, const FcChar8 *s2); DescriptionReturns the location of s2 in s1. Returns NULL if s2 is not present in s1. This test will operate properly with UTF8 encoded strings.
FcStrSetMember – check set for membership Synopsis#include <fontconfig/fontconfig.h> FcBool FcStrSetMember (FcStrSet *set, const FcChar8 *s); DescriptionReturns whether s is a member of set.
FcStrSetEqual – check sets for equality Synopsis#include <fontconfig/fontconfig.h> FcBool FcStrSetEqual (FcStrSet *set_a, FcStrSet *set_b); DescriptionReturns whether set_a contains precisely the same strings as set_b. Ordering of strings within the two sets is not considered.
FcStrSetDestroy – destroy a string set Synopsis#include <fontconfig/fontconfig.h> void FcStrSetDestroy (FcStrSet *set); DescriptionDestroys set.
FcStrSetDel – delete from a string set Synopsis#include <fontconfig/fontconfig.h> FcBool FcStrSetDel (FcStrSet *set, const FcChar8 *s); DescriptionRemoves s from set, returning FcTrue if s was a member else FcFalse.
FcStrSetCreate – create a string set Synopsis#include <fontconfig/fontconfig.h> FcStrSet * FcStrSetCreate (void); DescriptionCreate an empty set.
FcStrSetAddFilename – add a filename to a string set Synopsis#include <fontconfig/fontconfig.h> FcBool FcStrSetAddFilename (FcStrSet *set, const FcChar8 *s); DescriptionAdds a copy s to set, The copy is created with FcStrCopyFilename so that leading ‘~’ values are replaced with the value of the HOME environment variable.
FcStrSetAdd – add to a string set Synopsis#include <fontconfig/fontconfig.h> FcBool FcStrSetAdd (FcStrSet *set, const FcChar8 *s); DescriptionAdds a copy of s to set.
