The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
FcValueEqual – Test two values for equality Synopsis #include <fontconfig/fontconfig.h> FcBool FcValueEqual (FcValue v_a, FcValue v_b); Description Compares two values. Integers and Doubles are compared as numbers; otherwise the two values have to be the same type to be considered equal. Strings are compared ignoring case.
FcValueDestroy – Free a value Synopsis #include <fontconfig/fontconfig.h> void FcValueDestroy (FcValue v); Description Frees any memory referenced by v. Values of type FcTypeString, FcTypeMatrix and FcTypeCharSet reference memory, the other types do not.
FcUtf8ToUcs4 – convert UTF-8 to UCS4 Synopsis #include <fontconfig/fontconfig.h> int FcUtf8ToUcs4 (FcChar8 *src, FcChar32 *dst, int len); Description Converts the next Unicode char from src into dst and returns the number of bytes containing the char. src must be at least len bytes long.
FcUtf8Len – count UTF-8 encoded chars Synopsis #include <fontconfig/fontconfig.h> FcBool FcUtf8Len (FcChar8 *src, int len, int *nchar, int *wchar); Description Counts the number of Unicode chars in len bytes of src. Places that count in nchar. wchar contains 1, 2 or 4 depending on the number of bytes needed to hold the largest Unicode char…
FcUtf16ToUcs4 – convert UTF-16 to UCS4 Synopsis #include <fontconfig/fontconfig.h> int FcUtf16ToUcs4 (FcChar8 *src, FcEndian endian, FcChar32 *dst, int len); Description Converts the next Unicode char from src into dst and returns the number of bytes containing the char. src must be at least len bytes long. Bytes of src are combined into 16-bit units according…
FcUtf16Len – count UTF-16 encoded chars Synopsis #include <fontconfig/fontconfig.h> FcBool FcUtf16Len (FcChar8 *src, FcEndian endian, int len, int *nchar, int *wchar); Description Counts the number of Unicode chars in len bytes of src. Bytes of src are combined into 16-bit units according to endian. Places that count in nchar. wchar contains 1, 2 or 4…
FcUcs4ToUtf8 – convert UCS4 to UTF-8 Synopsis #include <fontconfig/fontconfig.h> int FcUcs4ToUtf8 (FcChar32 src, FcChar8 dst[FC_UTF8_MAX_LEN]); Description Converts the Unicode char from src into dst and returns the number of bytes needed to encode the char.
FcToLower – convert upper case ASCII to lower case Synopsis #include <fontconfig/fontconfig.h> FcChar8 FcToLower (FcChar8c); Description This 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); Description Returns 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); Description Returns 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); Description Returns 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); Description Returns 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); Description Destroys set.
FcStrSetDel – delete from a string set Synopsis #include <fontconfig/fontconfig.h> FcBool FcStrSetDel (FcStrSet *set, const FcChar8 *s); Description Removes 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); Description Create an empty set.
FcStrSetAddFilename – add a filename to a string set Synopsis #include <fontconfig/fontconfig.h> FcBool FcStrSetAddFilename (FcStrSet *set, const FcChar8 *s); Description Adds 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); Description Adds a copy of s to set.
FcStrPlus – concatenate two strings Synopsis #include <fontconfig/fontconfig.h> FcChar8 * FcStrPlus (const FcChar8 *s1, const FcChar8 *s2); Description This function allocates new storage and places the concatenation of s1 and s2 there, returning the new string.
FcStrListNext – get next string in iteration Synopsis #include <fontconfig/fontconfig.h> FcChar8 * FcStrListNext (FcStrList *list); Description Returns the next string in list.
FcStrListFirst – get first string in iteration Synopsis #include <fontconfig/fontconfig.h> void FcStrListFirst (FcStrList *list); Description Returns the first string in list. Since version 2.11.0
