NAME

6       TIFFWarning, TIFFSetWarningHandler - library warning interface
7

SYNOPSIS

9       #include <tiffio.h>
10
11       void TIFFWarning(const char *module, const char *fmt, ...)
12
13       #include <stdargh.h>
14
15       typedef void (*TIFFWarningHandler)(const char *module, const char *fmt,
16       va_list ap);
17
18       TIFFWarningHandler TIFFSetWarningHandler(TIFFWarningHandler handler);
19

DESCRIPTION

21       TIFFWarning invokes the library-wide warning handler function to  (nor‐
22       mally)  write  a warning message to the stderr.  The fmt parameter is a
23       printf(3S) format string, and any number arguments can be supplied. The
24       module  parameter  is interpreted as a string that, if non-zero, should
25       be printed before the message; it typically is  used  to  identify  the
26       software module in which a warning is detected.
27
28       Applications  that  desire to capture control in the event of a warning
29       should use TIFFSetWarningHandler to override the default  warning  han‐
30       dler.  A NULL (0) warning handler function may be installed to suppress
31       error messages.
32

RETURN VALUES

34       TIFFSetWarningHandler returns a reference to the  previous  error  han‐
35       dling function.
