49 * This module implements Samba's debugging utility.
51 * The syntax of a debugging log file is represented as:
53 * <debugfile> :== { <debugmsg> }
55 * <debugmsg> :== <debughdr> '\n' <debugtext>
57 * <debughdr> :== '[' TIME ',' LEVEL ']' [ [FILENAME ':'] [FUNCTION '()'] ]
59 * <debugtext> :== { <debugline> }
61 * <debugline> :== TEXT '\n'
63 * TEXT is a string of characters excluding the newline character.
64 * LEVEL is the DEBUG level of the message (an integer in the range 0..10).
65 * TIME is a timestamp.
66 * FILENAME is the name of the file from which the debug message was generated.
67 * FUNCTION is the function from which the debug message was generated.
69 * Basically, what that all means is:
71 * - A debugging log file is made up of debug messages.
73 * - Each debug message is made up of a header and text. The header is
74 * separated from the text by a newline.
76 * - The header begins with the timestamp and debug level of the message
77 * enclosed in brackets. The filename and function from which the
78 * message was generated may follow. The filename is terminated by a
79 * colon, and the function name is terminated by parenthesis.
81 * - The message text is made up of zero or more lines, each terminated by
85 /* state variables for the debug system */

137 * to build the formatted output.
139 * format_pos - Marks the first free byte of the format_bufr.
142 * log_overflow - When this variable is true, never attempt to check the
143 * size of the log. This is a hack, so that we can write
144 * a message using DEBUG, from open_logs() when we
