TIFFWarning, TIFFSetWarningHandler — library warning interface


#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);


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.
