.SH NAME
TIFFWarning, TIFFSetWarningHandler \- library warning interface
.SH SYNOPSIS
.B "#include <tiffio.h>"
.sp
.BI "void TIFFWarning(const char *" module ", const char *" fmt ", " ... ")"
.sp
.B "#include <stdargh.h>"
.sp
.BI "typedef void (*TIFFWarningHandler)(const char *" module ", const char *" fmt ", va_list " ap ");"
.sp
.BI "TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler " handler ");"
.SH DESCRIPTION
.I TIFFWarning
invokes the library-wide warning handler function to (normally) write a
warning 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 is interpreted as a string that, if non-zero, should be printed
before the message; it typically is used to identify the software module in
which a warning is detected.
.PP
Applications that desire to capture control in the event of a warning should
use
.IR TIFFSetWarningHandler
to override the default warning handler.
A
.SM NULL
(0) warning handler function may be installed to suppress error messages.
.SH "RETURN VALUES"
.IR TIFFSetWarningHandler
returns a reference to the previous error handling function.
.SH "SEE ALSO"
.BR TIFFError (3TIFF),
.BR libtiff (3TIFF),
.BR printf (3)
