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_t diroff)


DESCRIPTION

       TIFFSetDirectory changes the current directory and reads its contents
       with TIFFReadDirectory.  The parameter dirnum specifies the
       subfile/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.
