TIFFError, TIFFSetErrorHandler \- library error handling interface
|
|
|

|

|

|
|
|
.B "#include <tiffio.h>"
|
|
|
|

|
|
|
|
.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.
