81 * Parse input one character at a time.
82 *
83 * Input: state - A pointer to a token variable. This is used to
84 * maintain the parser state between calls. For
85 * each input stream, you should set up a separate
86 * state variable and initialize it to dbg_null.
87 * Pass a pointer to it into this function with each
88 * character in the input stream. See dbg_test()
89 * for an example.
90 * c - The "current" character in the input stream.
91 *
92 * Output: A token.
93 * The token value will change when delimiters are found,
94 * which indicate a transition between syntactical objects.
95 * Possible return values are:
96 *
97 * dbg_null - The input character was an end-of-line.
98 * This resets the parser to its initial state
99 * in preparation for parsing the next line.
100 * dbg_eof - Same as dbg_null, except that the character
101 * was an end-of-file.
102 * dbg_ignore - Returned for whitespace and delimiters.
103 * These lexical tokens are only of interest
104 * to the parser.
105 * dbg_header - Indicates the start of a header line. The
106 * input character was '[' and was the first on
107 * the line.
108 * dbg_timestamp - Indicates that the input character was part
109 * of a header timestamp.
110 * dbg_level - Indicates that the input character was part
111 * of the debug-level value in the header.
112 * dbg_sourcefile - Indicates that the input character was part
113 * of the sourcefile name in the header.
114 * dbg_function - Indicates that the input character was part
115 * of the function name in the header.
116 * dbg_lineno - Indicates that the input character was part
117 * of the DEBUG call line number in the header.
118 * dbg_message - Indicates that the input character was part
119 * of the DEBUG message text.
