37 * The debug macros are used if you compile with DEBUG defined.
41 * DEBUG_puts("string")
42 * DEBUG_printf(("format string", arg, arg, ...));
44 * Note the extra parenthesis around the DEBUG_printf macro...
46 * Newlines are not required on the end of messages, as both add one when
49 * If the first character is a digit, then it represents the "log level" of the
50 * message from 0 to 9. The default level is 1. The following defines the
51 * current levels we use:
53 * 0 = public APIs, other than value accessor functions
54 * 1 = return values for public APIs
55 * 2 = public value accessor APIs, progress for public APIs
56 * 3 = return values for value accessor APIs
57 * 4 = private APIs, progress for value accessor APIs
58 * 5 = return values for private APIs
59 * 6 = progress for private APIs
60 * 7 = static functions
61 * 8 = return values for static functions
62 * 9 = progress for static functions
64 * The DEBUG_set macro allows an application to programmatically enable (or
65 * disable) debug logging. The arguments correspond to the CUPS_DEBUG_LOG,
66 * CUPS_DEBUG_LEVEL, and CUPS_DEBUG_FILTER environment variables.
