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, uint32 diroff)

DESCRIPTION
       TIFFSetDirectory	changes	the current directory and reads	 its  contents
       with TIFFReadDirectory.	The parameter dirnum specifies the subfile/di-
       rectory 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 en-
       countered 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.
