TIFFWarning(3T)TIFFWarning(3T)NAME
TIFFWarning, TIFFSetWarningHandler - library warning
interface
SYNOPSIS
#include <tiffio.h>
void TIFFWarning(const char* module, const char* fmt, ...)
#include <stdargh.h>
typedef void (*TIFFWarningHandler)(const char* module,
const char* fmt, va_list ap);
TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHan-
dler handler);
DESCRIPTIONTIFFWarning invokes the library-wide warning handler func-
tion 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 iden-
tify 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.
