|
||
|
|
* Description:
|
||
|
|
* This function is responsible for logging information to the NT machine's
|
||
|
|
* System Event log. The Event to log is specified by the parameter
|
||
|
|
* anEventId, which is defined in the file lmerrlog.h. The anInfoStr
|
||
|
|
* parameter is used to specify additional information to be merged with
|
||
|
|
* the Event message.
|
||
|
|
*
|
||
|
|
* Parameters:
|
||
|
|
* anEventId - the id of the Event to log
|
||
|
|
* anInfoStr - additional information to merge with the message
|
||
|
|
* or NULL if there is no additional information.
|
||
|
|
* anErrVal - the error code as reported by GetLastError().
|
||
|
|
*
|
||
|
|
* Returns:
|
||
|
|
* TRUE - if the Event was logged successfully
|
||
|
|
* FALSE - if there was an error logging the Event
|

|
