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.
TIFFSetWarningHandler returns a reference to the previous error handling function.
