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(TIFFWarningHan-
       dler handler);

DESCRIPTION
       TIFFWarning invokes the library-wide warning handler func-
       tion to (normally) write a warning message to the  stderr.
       The  fmt  parameter is a printf(f) 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  iden-
       tify 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.
