TIFFWarning(3T)

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 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.
