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