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.
FcMatrixMultiply – Multiply matrices Synopsis #include <fontconfig/fontconfig.h> void FcMatrixMultiply (FcMatrix *result, const FcMatrix *matrix1, const FcMatrix *matrix2); Description FcMatrixMultiply multiplies matrix1 and matrix2 storing the result in result.
FcMatrixInit – initialize an FcMatrix structure Synopsis #include <fontconfig/fontconfig.h> void FcMatrixInit (FcMatrix *matrix); Description FcMatrixInit initializes matrix to the identity matrix.
FcMatrixEqual – Compare two matrices Synopsis #include <fontconfig/fontconfig.h> void FcMatrixEqual (const FcMatrix *matrix1, const FcMatrix *matrix2); Description FcMatrixEqual compares matrix1 and matrix2 returning FcTrue when they are equal and FcFalse when they are not.
FcMatrixCopy – Copy a matrix Synopsis #include <fontconfig/fontconfig.h> void FcMatrixCopy (const FcMatrix *matrix); Description FcMatrixCopy allocates a new FcMatrix and copies mat into it.
FcLangSetUnion – Add langsets Synopsis #include <fontconfig/fontconfig.h> FcLangSet * FcLangSetUnion (const FcLangSet *ls_a, const FcLangSet *ls_b); Description Returns a set including only those languages found in either ls_a or ls_b. Since version 2.9.0
FcLangSetSubtract – Subtract langsets Synopsis #include <fontconfig/fontconfig.h> FcLangSet * FcLangSetSubtract (const FcLangSet *ls_a, const FcLangSet *ls_b); Description Returns a set including only those languages found in ls_a but not in ls_b. Since version 2.9.0
FcLangSetHash – return a hash value for a langset Synopsis #include <fontconfig/fontconfig.h> FcChar32 FcLangSetHash (const FcLangSet *ls); Description This function returns a value which depends solely on the languages supported by ls. Any language which equals ls will have the same result from FcLangSetHash. However, two langsets with the same hash value may not be…
FcLangSetHasLang – test langset for language support Synopsis #include <fontconfig/fontconfig.h> FcLangResult FcLangSetHasLang (const FcLangSet *ls, const FcChar8 *lang); Description FcLangSetHasLang checks whether ls supports lang. If ls has a matching language and territory pair, this function returns FcLangEqual. If ls has a matching language but differs in which territory that language is for, this function…
FcLangSetGetLangs – get the list of languages in the langset Synopsis #include <fontconfig/fontconfig.h> FcStrSet * FcLangSetGetLangs (const FcLangSet *ls); Description Returns a string set of all languages in langset.
FcLangSetEqual – test for matching langsets Synopsis #include <fontconfig/fontconfig.h> FcBool FcLangSetEqual (const FcLangSet *ls_a, const FcLangSet *ls_b); Description Returns FcTrue if and only if ls_a supports precisely the same language and territory combinations as ls_b.
FcLangSetDestroy – destroy a langset object Synopsis #include <fontconfig/fontconfig.h> void FcLangSetDestroy (FcLangSet *ls); Description FcLangSetDestroy destroys a FcLangSet object, freeing all memory associated with it.
FcLangSetDel – delete a language from a langset Synopsis #include <fontconfig/fontconfig.h> FcBool FcLangSetDel (FcLangSet *ls, const FcChar8 *lang); Description lang is removed from ls. lang should be of the form Ll-Tt where Ll is a two or three letter language from ISO 639 and Tt is a territory from ISO 3166. Since version 2.9.0
FcLangSetCreate – create a langset object Synopsis #include <fontconfig/fontconfig.h> FcLangSet * FcLangSetCreate (void); Description FcLangSetCreate creates a new FcLangSet object.
FcLangSetCopy – copy a langset object Synopsis #include <fontconfig/fontconfig.h> FcLangSet * FcLangSetCopy (const FcLangSet *ls); Description FcLangSetCopy creates a new FcLangSet object and populates it with the contents of ls.
FcLangSetContains – check langset subset relation Synopsis #include <fontconfig/fontconfig.h> FcBool FcLangSetContains (const FcLangSet *ls_a, const FcLangSet *ls_b); Description FcLangSetContains returns FcTrue if ls_a contains every language in ls_b. ls_a will ‘contain’ a language from ls_b if ls_a has exactly the language, or either the language or ls_a has no territory.
FcLangSetCompare – compare language sets Synopsis #include <fontconfig/fontconfig.h> FcLangResult FcLangSetCompare (const FcLangSet *ls_a, const FcLangSet *ls_b); Description FcLangSetCompare compares language coverage for ls_a and ls_b. If they share any language and territory pair, this function returns FcLangEqual. If they share a language but differ in which territory that language is for, this function returns FcLangDifferentTerritory….
FcLangSetAdd – add a language to a langset Synopsis #include <fontconfig/fontconfig.h> FcBool FcLangSetAdd (FcLangSet *ls, const FcChar8 *lang); Description lang is added to ls. lang should be of the form Ll-Tt where Ll is a two or three letter language from ISO 639 and Tt is a territory from ISO 3166.
FcLangNormalize – Normalize the language string Synopsis #include <fontconfig/fontconfig.h> FcChar8 * FcLangNormalize (const FcChar8 *lang); Description Returns a string to make lang suitable on fontconfig. Since version 2.10.91
FcLangGetCharSet – Get character map for a language Synopsis #include <fontconfig/fontconfig.h> const FcCharSet * FcLangGetCharSet (const FcChar8 *lang); Description Returns the FcCharMap for a language.
FcIsUpper – check for upper case ASCII character Synopsis #include <fontconfig/fontconfig.h> FcBool FcIsUpper (FcChar8c); Description This macro checks whether c is a upper case ASCII letter.
