The OpenBackupEventLog function opens a handle of a backup event log. This handle can be used with the BackupEventLog function.
HANDLE OpenBackupEventLog(
| LPCTSTR lpUNCServerName, | // backup file server name | 
| LPCTSTR lpFileName | // backup filename | 
| ); | 
If the function succeeds, the return value is a handle of the backup event log.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
If the backup filename specifies a remote server, lpUNCServerName must be NULL. You cannot use this function to open a file on a remote server.
