TIFFSetDirectory(3T)			     TIFFSetDirectory(3T)

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, uint32 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(3T) rou-
       tine.

       %s: Error fetching directory count.  An error was  encoun-
       tered while reading the ``directory count'' field.

       %s:  Error  fetching directory link.  An error was encoun-
       tered while reading the ``link value'' that points to  the
       next directory in a file.
