# TIFFError(3t)

library error handling interface

## 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.
