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.
