<H2>DESCRIPTION</H2>
<I>TIFFWarning</I>
invokes the library-wide warning handler function
to (normally) write a warning message to the
<B>stderr</B>.
The
<I>fmt</I>
parameter is a
<I><A HREF="printf.3s.html">printf</A></I>(3S)
format string, and any number arguments can be supplied.
The
<I>module</I>
parameter is interpreted as a string that, if non-zero,
should be printed before the message; it typically
is used to identify the software module in which a warning
is detected.
<P>
Applications that desire to capture control in the event of a warning
should use
<I>TIFFSetWarningHandler</I>
to override the default warning handler.
A
<FONT SIZE="-1">NULL</FONT>
(0) warning handler function may be installed to
suppress error messages.
<A NAME="lbAE">&nbsp;</A>
<H2>RETURN VALUES</H2>
<I>TIFFSetWarningHandler</I>
returns a reference to the previous error handling function.
