RedHat 9 (Linux i386) - man page for tiffsetdirectory (redhat section 3T)

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 TIFFReadDirec-
       tory.  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 speci-
       fies a non-existent directory, or if an error was encountered  while  reading  the  direc-
       tory'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 ``direc-
       tory 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.
