TIFFWarning(3T)	  Image	Format Library C++ Reference Manual    TIFFWarning(3T)

NAME    [Toc]    [Back]

     TIFFWarning, TIFFSetWarningHandler	- library warning interface

SYNOPSIS    [Toc]    [Back]

     #include <tiffio.h>
     void TIFFWarning(const char* module, const	char* fmt, ...)

     #include <stdargh.h>
     typedef void (*TIFFWarningHandler)(const char* module, const char*	fmt,
     va_list ap);
     TIFFWarningHandler	TIFFSetWarningHandler(TIFFWarningHandler handler);

DESCRIPTION    [Toc]    [Back]

     TIFFWarning invokes the library-wide warning handler function to
     (normally)	write a	warning	message	to the stderr.	The fmt	parameter is a
     printf(3S)	format string, and any number arguments	can be supplied.  The
     module 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.

     Applications that desire to capture control in the	event of a warning
     should use	TIFFSetWarningHandler to override the default warning handler.
     A NULL (0)	warning	handler	function may be	installed to suppress error
     messages.

RETURN VALUES    [Toc]    [Back]

     TIFFSetWarningHandler returns a reference to the previous error handling
     function.
