| 32 | * The debug macros are used if you compile with DEBUG defined. | |
| 33 | * | |
| 34 | * Usage: | |
| 35 | * | |
| 36 | * DEBUG_puts("string") | |
| 37 | * DEBUG_printf(("format string", arg, arg, ...)); | |
| 38 | * | |
| 39 | * Note the extra parenthesis around the DEBUG_printf macro... | |
| 40 | * | |
| 41 | * Newlines are not required on the end of messages, as both add one when | |
| 42 | * writing the output. | |
| 43 | * | |
| 44 | * If the first character is a digit, then it represents the "log level" of the | |
| 45 | * message from 0 to 9. The default level is 1. The following defines the | |
| 46 | * current levels we use: | |
| 47 | * | |
| 48 | * 0 = public APIs, other than value accessor functions | |
| 49 | * 1 = return values for public APIs | |
| 50 | * 2 = public value accessor APIs, progress for public APIs | |
| 51 | * 3 = return values for value accessor APIs | |
| 52 | * 4 = private APIs, progress for value accessor APIs | |
| 53 | * 5 = return values for private APIs | |
| 54 | * 6 = progress for private APIs | |
| 55 | * 7 = static functions | |
| 56 | * 8 = return values for static functions | |
| 57 | * 9 = progress for static functions | |
