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(TIFFWarningHandler
handler);
DESCRIPTION¶
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.
