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 (nor-
mally) 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 han-
dler. A NULL (0) warning handler function may be installed to suppress
error messages.
RETURN VALUES
TIFFSetWarningHandler returns a reference to the previous error han-
dling function.
