SYNOPSIS
       #include <tiffio.h>
       uint32 TIFFCurrentRow(TIFF* tif)
       tstrip_t TIFFCurrentStrip(TIFF* tif)
       ttile_t TIFFCurrentTile(TIFF* tif)
       tdir_t TIFFCurrentDirectory(TIFF* tif)
       int TIFFLastDirectory(TIFF* tif)
       int TIFFFileno(TIFF* tif)
       char* TIFFFileName(TIFF* tif)
       int TIFFGetMode(TIFF* tif)
       int TIFFIsTiled(TIFF* tif)
       int TIFFIsByteSwapped(TIFF* tif)

       const char* TIFFGetVersion(void)

DESCRIPTION
       The following routines return status information about  an
       open TIFF file.

       TIFFCurrentDirectory  returns  the  index  of  the current
       directory (directories are numbered starting at 0).   This
       number  is suitable for use with the TIFFSetDirectory rou-
       tine.

       TIFFLastDirectory returns a non-zero value if the  current
       directory  is  the  last	 directory in the file; otherwise
       zero is returned.

       TIFFCurrentRow,	TIFFCurrentStrip,  and	 TIFFCurrentTile,
       return  the  current  row,  strip, and tile, respectively,
       that is being read or written.  These values  are  updated
       each time a read or write is done.

       TIFFFileno  returns the underlying file descriptor used to
       access the TIFF image in the filesystem.

       TIFFFileName  returns  the  pathname  argument  passed  to
       TIFFOpen or TIFFFdOpen.

       TIFFGetMode  returns  the  mode	with which the underlying
       file was opened.	 On  UNIX  systems,  this  is  the  value
       passed to the open(2) system call.

       TIFFIsTiled returns a non-zero value if the image data has
       a tiled organization.  Zero is returned if the image  data
       is organized in strips.

       TIFFIsByteSwapped  returns  a  non-zero value if the image
       data was in a different byte-order than the host	 machine.
       Zero  is	 returned  if  the TIFF file and local host byte-
       orders are the same.  Note that TIFFReadTile(),	TIFFRead-
       Strip()	and TIFFReadScanline() functions already normally
       perform byte swapping to local host order if needed.

       TIFFIsUpSampled returns a non-zero  value  if  image  data
       returned	 through the read interface routines is being up-
       sampled.	 This can be useful to applications that want  to
       calculate  I/O  buffer sizes to reflect this usage (though
       the usual strip and tile size routines already do this).

       TIFFIsMSB2LSB returns a non-zero value if the  image  data
       is  being returned with bit 0 as the most significant bit.

       TIFFGetVersion returns an ASCII string that has a  version
       stamp for the TIFF library software.

DIAGNOSTICS
       None.
