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 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(3T) 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.
