NAME

TIFFWarning, TIFFSetWarningHandler - library warning interface

SYNOPSIS

#include <tiffio.h>

void TIFFWarning(const char *module, const char *fmt, ...)

#include <stdarg.h>

typedef void (*TIFFWarningHandler)(const char *module, const char
*fmt, va_list ap);

TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler handler);

DESCRIPTION

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

TIFFSetWarningHandler returns a reference to the previous error
handling function.
