SYNOPSIS
     #include <tiffio.h>
     uint32 TIFFCurrentRow(TIFF* tif)
     tstript TIFFCurrentStrip(TIFF* tif)
     ttilet TIFFCurrentTile(TIFF* tif)
     tdirt TIFFCurrentDirectory(TIFF* tif)
     int TIFFLastDirectory(TIFF* tif)
     int TIFFFileno(TIFF* tif)
     char* TIFFFileName(TIFF* tif)
     int TIFFGetMode(TIFF* tif)
     int TIFFIsTiled(TIFF* tif)

     int TIFFIsUpSampled(TIFF* tif)
     int TIFFIsMSB2LSB(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 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 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
     image data and local host byte-orders are the same.  Data samples that
     are more than 8 bits wide must be byte-swapped by the application.




                                                                        Page 1

     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.
