TIFFError(3T)
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 handler);
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 number 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.
