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

(0) warning handler function may be installed to suppress error messages.

TIFFSetWarningHandler returns a reference to the previous error handling function.
