27 | TIFFWarning, TIFFSetWarningHandler \- library warning interface | |

38 | .SH DESCRIPTION | |
39 | .I TIFFWarning | |
40 | invokes the library-wide warning handler function to (normally) write a | |
41 | warning message to the | |
42 | .BR stderr . | |
43 | The | |
44 | .I fmt | |
45 | parameter is a | |
46 | .IR printf (3S) | |
47 | format string, and any number arguments can be supplied. The | |
48 | .I module | |
49 | parameter is interpreted as a string that, if non-zero, should be printed | |
50 | before the message; it typically is used to identify the software module in | |
51 | which a warning is detected. | |
52 | .PP | |
53 | Applications that desire to capture control in the event of a warning should | |
54 | use | |
55 | .IR TIFFSetWarningHandler | |
56 | to override the default warning handler. | |
57 | A | |
58 | .SM NULL | |
59 | (0) warning handler function may be installed to suppress error messages. | |
60 | .SH "RETURN VALUES" | |
61 | .IR TIFFSetWarningHandler | |
62 | returns a reference to the previous error handling function. | |
