Module Name:
tracelog.c
Abstract:
Sample trace control program. Allows user to start, stop event tracing
// end_sdk
Author:
Jee Fung Pang (jeepang) 03-Dec-1997
Revision History:
Insung Park (insungp) 28-Nov-2000
Now tracelog can be used to set the registry keys to start or stop
GlobalLogger. Other options also works except a few (such as -enable).
e.g.
tracelog -start GlobalLogger
tracelog -stop GlobalLogger
tracelog -q GlobalLogger
However, "-start" option does not start GlobalLogger immediately. The
machine must be rebooted. "-stop" option resets the registry keys and
stop GlobalLogger.
Users can use other options to customize the GlobalLogger sessions
such as minimum and maximum buffers, buffer size, flush timer, and so on.
One catch is, if any of the enable flags is set, GlobalLogger turns into
NT Kernel Logger and its instance vanishes. Any attempt to access
GlobalLogger with its name will fail with ERROR_WMI_INSTANCE_NOT_FOUND.
"-stop" option will still reset registry keys so that the next time the
machine boots GlobalLogger will not start.
If any of the flags is set, users should access NT Kernel Logger to
control it.
Modified/updated functions include GetGlobalLoggerSettings,
SetGlobalLoggerSettings, main, PrintLoggerStatus.
Insung Park (insungp) 19-Dec-2000
Changed trace function calls so that tracelog can be used on Win2K.
FlushTrace and EnumTraceGuids are not implemented on Win2K, but they do
not stop the execution of tracelog. An attempt to use FlushTrace or
EnumTraceGuids on W2K will generate an error message.
Fixed "-flags -1" bug. tracelog does not accept any flag with MSB=1.
Insung Park (insungp) 21-Dec-2000
Added a version display.
Fixed PrintHelpMessage() so that options not available on Win2K will
not be printed. ("-paged", "-flush", "-enumguid", "-append", "-newfile",
"-eflag", "-ls", "-gs")
Cleaned up the if blocks in main() so that tracelog frees allocated
space properly before exiting regardless of error status.

Since it is a standalone utility, there is no need for extensive comments.
Routine Description:
Depending on the value given in "StartValue", it sets or resets event
trace registry. If the StartValue is 0 (Global logger off), it deletes
all the keys (that the user may have set previsouly).
Users are allowed to set or reset individual keys using this function,
but only when "-start GlobalLogger" is used.
The section that uses non NTAPIs is not guaranteed to work.
Arguments:
StartValue - The "Start" value to be set in the registry.
0: Global logger off
1: Global logger on
LoggerInfo - The poniter to the resident EVENT_TRACE_PROPERTIES instance.
whose members are used to set registry keys.
ClockType - The type of the clock to be set.
Return Value:
Error Code defined in winerror.h : If the function succeeds,
it returns ERROR_SUCCESS.
