* DesiredAccess Desired access to the file
* ObjectAttributes Structure describing the file
* IoStatusBlock Receives information about the operation on return
* AllocationSize Initial size of the file in bytes
* FileAttributes Attributes to create the file with
* ShareAccess Type of shared access the caller would like to the file
* CreateDisposition Specifies what to do, depending on whether the file already exists
* CreateOptions Options for creating a new file
