FcCharSetCreate 3 FcCharSetCreate Create an empty character set #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetCreate void FcCharSetCreate allocates and initializes a new empty character set object. Fontconfig version &version; FcCharSetDestroy 3 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. Fontconfig version &version; FcCharSetAddChar 3 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. Fontconfig version &version; FcCharSetDelChar 3 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. Fontconfig version &version; FcCharSetCopy 3 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. Fontconfig version &version; FcCharSetEqual 3 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. Fontconfig version &version; FcCharSetIntersect 3 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. Fontconfig version &version; FcCharSetUnion 3 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. Fontconfig version &version; FcCharSetSubtract 3 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. Fontconfig version &version; FcCharSetMerge 3 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. Fontconfig version &version; FcCharSetHasChar 3 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. Fontconfig version &version; FcCharSetCount 3 FcCharSetCount Count entries in a charset #include <fontconfig/fontconfig.h> FcChar32 FcCharSetCount const FcCharSet *a Returns the total number of Unicode chars in a. Fontconfig version &version; FcCharSetIntersectCount 3 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. Fontconfig version &version; FcCharSetSubtractCount 3 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. Fontconfig version &version; FcCharSetIsSubset 3 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. Fontconfig version &version; FcCharSetFirstPage 3 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 marking the first page of Unicode coverage of a. Returns the base of the array. next contains the next page in the font. Fontconfig version &version; FcCharSetNextPage 3 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 marking the Unicode coverage of a for page *next. Returns the base of the array. next contains the next page in the font. Fontconfig version &version; FcCharSetCoverage 3 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. Fontconfig version &version; FcCharSetNew 3 FcCharSetNew DEPRECATED alias for FcCharSetCreate #include <fontconfig/fontconfig.h> FcCharSet * FcCharSetNew void FcCharSetNew is a DEPRECATED alias for FcCharSetCreate.
