NAME

       TIFFWarning, TIFFSetWarningHandler - library warning interface

SYNOPSIS

       #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

       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 han-
       dler.  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.
