OpenEventLog function

Applies to: desktop apps only

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
