OpenEventLog

OpenEventLog

The OpenEventLog function opens a handle to an event log.

HANDLE OpenEventLog(
  LPCTSTR lpUNCServerName,  // pointer to server name
  LPCTSTR lpSourceName   // pointer to source name
);
 

Parameters

lpUNCServerName

Pointer 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.

lpSourceName

Pointer to a null-terminated string that specifies the name of the logfile that the returned handle will reference. This can be the Application, Security, or System logfile, or a custom registered logfile. If a custom registered logfile name cannot be found, the event logging service opens the Application logfile, however, there will be no associated message or category string file.

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