This should be a nested class, but that breaks too many compilers.

Base address of the memory-mapped backing store.
|
|
|
File mode for mmaped file, if it is created.
|
|
|
Any special flags that need to be used for <mmap>.
|
|
|
Try to remap without knowing the faulting address. This parameter is ignored on platforms that know the faulting address (UNIX with SI_ADDR and Win32). |
|
|
What the minimim bytes of the initial segment should be.
|
|
|
Pointer to a security attributes object. Only used on NT.
|
|
|
Determines whether we set <base_addr_> or if mmap(2) selects it FIRSTCALL_FIXED The base address from the first call to mmap will be used for subsequent calls to mmap ALWAYS_FIXED The base address specified in base_addr will be used in all calls to mmap. NEVER_FIXED The base address will be selected by the OS for each call to mmap. Caution should be used with this mode since a call that requires the backing store to grow may change pointers that are cached by the application. |

Should each page be written eagerly to avoid surprises later on?
