TIFFSetDirectory(3TIFF) TIFFSetDirectory(3TIFF) NAME TIFFSetDirectory, TIFFSetSubDirectory - set the current directory for an open TIFF file SYNOPSIS #include <tiffio.h> int TIFFSetDirectory(TIFF *tif, tdir_t dirnum) int TIFFSetSubDirectory(TIFF *tif, uint64 diroff) DESCRIPTION TIFFSetDirectory changes the current directory and reads its contents with TIFFReadDirectory. The parameter dirnum specifies the sub- file/directory as an integer number, with the first directory numbered zero. TIFFSetSubDirectory acts like TIFFSetDirectory, except the directory is specified as a file offset instead of an index; this is required for accessing subdirectories linked through a SubIFD tag. RETURN VALUES On successful return 1 is returned. Otherwise, 0 is returned if dirnum or diroff specifies a non-existent directory, or if an error was encountered while reading the directory's contents. DIAGNOSTICS All error messages are directed to the TIFFError(3TIFF) routine. %s: Error fetching directory count. An error was encountered while reading the ``directory count'' field. %s: Error fetching directory link. An error was encountered while reading the ``link value'' that points to the next directory in a file.
