FcFreeTypeQueryAll man page
FcFreeTypeQueryAll — compute all patterns from font file (and index)
#include <fontconfig.h> #include <fcfreetype.h> unsigned int FcFreeTypeQueryAll (const FcChar8 *file, int id, FcBlanks *blanks, int *count, FcFontSet *set);
Constructs patterns found in 'file'. If id is -1, then all patterns found in 'file' are added to 'set'. Otherwise, this function works exactly like FcFreeTypeQuery(). The number of faces in 'file' is returned in 'count'. The number of patterns added to 'set' is returned. FcBlanks is deprecated, blanks is ignored and accepted only for compatibility with older code.
