<A NAME="lbAD">&nbsp;</A>
<H2>DESCRIPTION</H2>

The following routines return status information about an open
<FONT SIZE="-1">TIFF</FONT>
file.
<P>

<I>TIFFCurrentDirectory</I>

returns the index of the current directory (directories
are numbered starting at 0).
This number is suitable for use with the
<I>TIFFSetDirectory</I>

routine.
<P>

<I>TIFFLastDirectory</I>

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

<I>TIFFCurrentRow</I>,

<I>TIFFCurrentStrip</I>,

and
<I>TIFFCurrentTile</I>,

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.
<P>

<I>TIFFFileno</I>

returns the underlying file descriptor used to access the 
<FONT SIZE="-1">TIFF</FONT>
image in the filesystem.
<P>

<I>TIFFFileName</I>

returns the pathname argument passed to
<I>TIFFOpen</I>

or
<I>TIFFFdOpen</I>.

<P>

<I>TIFFGetMode</I>

returns the mode with which the underlying file was opened.
On
<FONT SIZE="-1">UNIX</FONT>
systems, this is the value passed to the
<I><A HREF="open+2">open</A></I>(2)

system call.
<P>

<I>TIFFIsTiled</I>

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

<I>TIFFIsByteSwapped</I>

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.
<P>

<I>TIFFIsUpSampled</I>

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).
<P>

<I>TIFFIsMSB2LSB</I>

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

<I>TIFFGetVersion</I>

returns an
<FONT SIZE="-1">ASCII</FONT>
string that has a version stamp for the 
<FONT SIZE="-1">TIFF</FONT>
library software.
