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.
