.SH NAME
TIFFError, TIFFSetErrorHandler \- library error handling interface
.SH SYNOPSIS
.B "#include <tiffio.h>"
.sp
.BI "void TIFFError(const char *" module ", const char *" fmt ", " ... ")"
.sp
.B "#include <stdarg.h>"
.sp
.BI "typedef void (*TIFFErrorHandler)(const char *" module ", const char *" fmt ", va_list " ap ");"
.br
.B "TIFFErrorHandler TIFFSetErrorHandler(TIFFErrorHandler handler);"
.SH DESCRIPTION
.I TIFFError
invokes the library-wide error handling function to (normally) write an error
message to the
.BR stderr .
The
.I fmt
parameter is a
.IR printf (3S)
format string, and any number arguments can be supplied. The
.I 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.
.PP
Applications that desire to capture control in the event of an error should
use
.IR TIFFSetErrorHandler
to override the default error handler.
A
.SM NULL
(0) error handling function may be installed to suppress error messages.
.SH "RETURN VALUES"
.IR TIFFSetErrorHandler
returns a reference to the previous error handling function.
.SH "SEE ALSO"
