* This module implements Samba's debugging utility.
38
* The syntax of a debugging log file is represented as:
40
* <debugfile> :== { <debugmsg> }
42
* <debugmsg> :== <debughdr> '\n' <debugtext>
44
* <debughdr> :== '[' TIME ',' LEVEL ']' [ [FILENAME ':'] [FUNCTION '()'] ]
46
* <debugtext> :== { <debugline> }
48
* <debugline> :== TEXT '\n'
50
* TEXT is a string of characters excluding the newline character.
51
* LEVEL is the DEBUG level of the message (an integer in the range 0..10).
52
* TIME is a timestamp.
53
* FILENAME is the name of the file from which the debug message was generated.
54
* FUNCTION is the function from which the debug message was generated.
56
* Basically, what that all means is:
58
* - A debugging log file is made up of debug messages.
60
* - Each debug message is made up of a header and text. The header is
61
* separated from the text by a newline.
63
* - The header begins with the timestamp and debug level of the message
64
* enclosed in brackets. The filename and function from which the
65
* message was generated may follow. The filename is terminated by a
66
* colon, and the function name is terminated by parenthesis.
68
* - The message text is made up of zero or more lines, each terminated by
72
/* -------------------------------------------------------------------------- **
75
* dbf - Global debug file handle.
76
* debugf - Debug file name.
77
* DEBUGLEVEL - System-wide debug message limit. Messages with message-
78
* levels higher than DEBUGLEVEL will not be processed.

Input: level - Debug level of the message (not the system-wide debug

cls - Debuglevel class of the calling module.

file - Pointer to a string containing the name of the file
971
from which this function was called, or an empty string

if the __FILE__ macro is not implemented.

func - Pointer to a string containing the name of the function

line - line number of the call to dbghdr, assuming __LINE__
