NAME
TIFFError, TIFFSetErrorHandler - library error handling
interface
SYNOPSIS
#include <tiffio.h> void TIFFError(const char* module, const char* fmt, ...) #include <stdarg.h> typedef void (*TIFFErrorHandler)(const char* module, const char* fmt, va_list ap); TIFFErrorHandler TIFFSetErrorHandler(TIFFErrorHandler han dler);
DESCRIPTION
TIFFError invokes the library-wide error handling function
to (normally) write an error message to the stderr. The
fmt parameter is a printf(3S) format string, and any num
ber arguments can be supplied. The module parameter, if
non-zero, is printed before the message; it typically is
used to identify the software module in which an error is
detected.
Applications that desire to capture control in the event
of an error should use TIFFSetErrorHandler to override the
default error handler. A NULL (0) error handling function
may be installed to suppress error messages.
RETURN VALUES
TIFFSetErrorHandler returns a reference to the previous
error handling function.
