FcCharSetCreate 3 Fontconfig &version; FcCharSetCreate Create an empty character set #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetCreate void FcCharSetCreate allocates and initializes a new empty character set object. FcCharSetDestroy 3 Fontconfig &version; FcCharSetDestroy Destroy a character set #include <fontconfig/fontconfig.h> void FcCharSetDestroy FcCharSet *fcs FcCharSetDestroy decrements the reference count fcs. If the reference count becomes zero, all memory referenced is freed. FcCharSetAddChar 3 Fontconfig &version; FcCharSetAddChar Add a character to a charset #include <fontconfig/fontconfig.h> FcBool FcCharSetAddChar FcCharSet *fcs FcChar32 ucs4 FcCharSetAddChar adds a single Unicode char to the set, returning FcFalse on failure, either as a result of a constant set or from running out of memory. FcCharSetDelChar 3 Fontconfig &version; FcCharSetDelChar Add a character to a charset #include <fontconfig/fontconfig.h> FcBool FcCharSetDelChar FcCharSet *fcs FcChar32 ucs4 FcCharSetDelChar deletes a single Unicode char from the set, returning FcFalse on failure, either as a result of a constant set or from running out of memory. version 2.9.0 FcCharSetCopy 3 Fontconfig &version; FcCharSetCopy Copy a charset #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetCopy FcCharSet *src Makes a copy of src; note that this may not actually do anything more than increment the reference count on src. FcCharSetEqual 3 Fontconfig &version; FcCharSetEqual Compare two charsets #include <fontconfig/fontconfig.h> FcBool FcCharSetEqual const FcCharSet *a const FcCharSet *b Returns whether a and b contain the same set of Unicode chars. FcCharSetIntersect 3 Fontconfig &version; FcCharSetIntersect Intersect charsets #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetIntersect const FcCharSet *a const FcCharSet *b Returns a set including only those chars found in both a and b. FcCharSetUnion 3 Fontconfig &version; FcCharSetUnion Add charsets #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetUnion const FcCharSet *a const FcCharSet *b Returns a set including only those chars found in either a or b. FcCharSetSubtract 3 Fontconfig &version; FcCharSetSubtract Subtract charsets #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetSubtract const FcCharSet *a const FcCharSet *b Returns a set including only those chars found in a but not b. FcCharSetMerge 3 Fontconfig &version; FcCharSetMerge Merge charsets #include <fontconfig/fontconfig.h> FcBool FcCharSetMerge FcCharSet *a const FcCharSet *b FcBool *changed Adds all chars in b to a. In other words, this is an in-place version of FcCharSetUnion. If changed is not NULL, then it returns whether any new chars from b were added to a. Returns FcFalse on failure, either when a is a constant set or from running out of memory. FcCharSetHasChar 3 Fontconfig &version; FcCharSetHasChar Check a charset for a char #include <fontconfig/fontconfig.h> FcBool FcCharSetHasChar const FcCharSet *fcs FcChar32 ucs4 Returns whether fcs contains the char ucs4. FcCharSetCount 3 Fontconfig &version; FcCharSetCount Count entries in a charset #include <fontconfig/fontconfig.h> FcChar32 FcCharSetCount const FcCharSet *a Returns the total number of Unicode chars in a. FcCharSetIntersectCount 3 Fontconfig &version; FcCharSetIntersectCount Intersect and count charsets #include <fontconfig/fontconfig.h> FcChar32 FcCharSetIntersectCount const FcCharSet *a const FcCharSet *b Returns the number of chars that are in both a and b. FcCharSetSubtractCount 3 Fontconfig &version; FcCharSetSubtractCount Subtract and count charsets #include <fontconfig/fontconfig.h> FcChar32 FcCharSetSubtractCount const FcCharSet *a const FcCharSet *b Returns the number of chars that are in a but not in b. FcCharSetIsSubset 3 Fontconfig &version; FcCharSetIsSubset Test for charset inclusion #include <fontconfig/fontconfig.h> FcBool FcCharSetIsSubset const FcCharSet *a const FcCharSet *b Returns whether a is a subset of b. FcCharSetFirstPage 3 Fontconfig &version; FcCharSetFirstPage Start enumerating charset contents #include <fontconfig/fontconfig.h> FcChar32 FcCharSetFirstPage const FcCharSet *a FcChar32[FC_CHARSET_MAP_SIZE] map FcChar32 *next Builds an array of bits in map marking the first page of Unicode coverage of a. *next is set to contains the base code point for the next page in a. Returns the base code point for the page, or FC_CHARSET_DONE if a contains no pages. As an example, if FcCharSetFirstPage returns 0x300 and fills map with 0xffffffff 0xffffffff 0x01000008 0x44300002 0xffffd7f0 0xfffffffb 0xffff7fff 0xffff0003 Then the page contains code points 0x300 through 0x33f (the first 64 code points on the page) because map[0] and map[1] both have all their bits set. It also contains code points 0x343 (0x300 + 32*2 + (4-1)) and 0x35e (0x300 + 32*2 + (31-1)) because map[2] has the 4th and 31st bits set. The code points represented by map[3] and later are left as an excercise for the reader ;). FcCharSetNextPage 3 Fontconfig &version; FcCharSetNextPage Continue enumerating charset contents #include <fontconfig/fontconfig.h> FcChar32 FcCharSetNextPage const FcCharSet *a FcChar32[FC_CHARSET_MAP_SIZE] map FcChar32 *next Builds an array of bits in map marking the Unicode coverage of a for page containing *next (see the FcCharSetFirstPage description for details). *next is set to contains the base code point for the next page in a. Returns the base of code point for the page, or FC_CHARSET_DONE if a does not contain *next. FcCharSetCoverage 3 Fontconfig &version; FcCharSetCoverage DEPRECATED return coverage for a Unicode page #include <fontconfig/fontconfig.h> FcChar32 FcCharSetCoverage const FcCharSet *a FcChar32page FcChar32[8]result DEPRECATED This function returns a bitmask in result which indicates which code points in page are included in a. FcCharSetCoverage returns the next page in the charset which has any coverage. FcCharSetNew 3 Fontconfig &version; FcCharSetNew DEPRECATED alias for FcCharSetCreate #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetNew void FcCharSetNew is a DEPRECATED alias for FcCharSetCreate.
