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

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

       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  cur-
       rent 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	TIFFF-
       dOpen.

       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 or-
       ganization. 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 TIFFRead-
       Tile(),	TIFFReadStrip()	 and TIFFReadScanline()	functions already nor-
       mally 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 re-
       turned 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.
