tiffwarning(3)
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);
DESCRIPTION
TIFFWarning 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.
