OpenEventLog function

Opens a handle to the specified event log.

Syntax


HANDLE OpenEventLog(
  _In_  LPCTSTR lpUNCServerName,
  _In_  LPCTSTR lpSourceName

Parameters

lpUNCServerName [in]

The Universal Naming Convention (UNC) name of the remote server on which the event log is to be opened. If this parameter is NULL, the local computer is used.

If you specify a custom log and it cannot be found, the event logging service opens the Application log; however, there will be no associated message or category string file.

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

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

Remarks

To close the handle to the event log, use the CloseEventLog function.
