NAME
TIFFWarning, TIFFSetWarningHandler - library warning interface
SYNOPSIS
#include <tiffio.h>
void TIFFWarning(const char *module, const char *fmt, ...)
#include <stdarg.h>
typedef void (*TIFFWarningHandler)(const char *module, const char *fmt, va_list ap);
TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler handler);
DESCRIPTION
TIFFWarning
invokes the library-wide warning handler function to (normally) write a
warning message to the
stderr.
The
fmt
parameter is a
printf(3S)
format string, and any number arguments can be supplied. The
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.
Applications that desire to capture control in the event of a warning should
use
TIFFSetWarningHandler
to override the default warning handler.
A
NULL
(0) warning handler function may be installed to suppress error messages.
RETURN VALUES
TIFFSetWarningHandler
returns a reference to the previous error handling function.
