OpenEventLog  18WKRLP 

The OpenEventLog function opens a handle of an event log.

HANDLE OpenEventLog(

    LPCTSTR lpUNCServerName,

// pointer to server name

    LPCTSTR lpSourceName

// pointer to source name

   );

 

 

Parameters

lpUNCServerName

Points to a null-terminated string that specifies the Universal Naming Convention (UNC) name of the server on which the event log is to be opened. If this parameter is NULL, the log is opened on the local computer.

lpSourceName

Points to a null-terminated string that specifies the name of the source that the returned handle will reference. The source name must be a subkey of a logfile entry under the EventLog key in the registry. For example, the source name WinApp would be valid if the registry had the following form:

HKEY_LOCAL_MACHINE

  System

    CurrentControlSet

      Services

        EventLog

          Application

            WinApp

          Security

          System

 

If the source name cannot be found, the event logging service uses the Application logfile with no message files for the event identifier or category.

 

Return Values

If the function succeeds, the return value is the handle of an event log.

If the function fails, the return value is NULL. To get extended error information, call GetLastError11C2VS7.
