/** Set diagnostic message display level for module no. IMODULE.
|
|
* (0 <= IMODULE < TLOG_MAXMODULES)
|
|
*
|
|
* MESSAGELEVEL (>=0) specifies the diagnostic message display level:
|
|
* only diagnostic messages with level values >= MESSAGELEVEL are printed
|
|
* (For example, level 10, 11, ...: outermost level;
|
|
* level 20, 21, ...: next inner level;
|
|
* ...
|
|
* level 50, 51, ...: innermost level)
|
|
*
|
|
* The message SUBLEVEL threshold is defined as MESSAGELEVEL%10
|
|
* (ranging from 0 to 9).
|
|
* Only those diagnostic messages with sublevel values >= SUBLEVEL threshold
|
|
* are displayed
|
|
* Usually, the SUBLEVEL threshold values are interpreted as
|
|
* 0 => print single message per selected procedure.
|
|
* 1...9 => print only messages upto selected sublevel.
|
|
*
|
|
* Setting MESSAGELEVEL to zero and FUNCTIONLIST to null for all modules
|
|
* disables debugging and printing of warning messages.
|
|
* (This is the initial configuration following the call to lterm_init.)
|
|
* Setting MESSAGELEVEL to 1 for atleast one module enables debugging and
|
|
* causes warning messages for all modules to be printed.
|
|
*
|
|
* FUNCTIONLIST is a colon-separated string of function names, e.g.,
|
|
* "func_a:func_b".
|
|
* Trace/log messages for functions in this list are always output
|
|
* if debugging is enabled provided the sublevel values exceed the threshold,
|
|
* regardless of full message level values.
|
|
* If FUNCTIONLIST contains a single method name without a class name, or a
|
|
* class name without a method name, then the missing portion is assumed
|
|
* to be wild-carded.
|
|
*
|
|
* Returns 0 on success, -1 otherwise (i.e., for invalid module numbers)
