Detailed Description

The maximum security guard over one cellblock: every release zeroes the cell first.

Note

EMBED_TABLE_LAYOUT asserts the thirteen members sit at consecutive EMBED_FUNCTION_POINTER_BYTES offsets, with nothing else.

The same thirteen entries, and no unzeroed release among them. Each zeroing runs before the cell's header goes free: the bytes are zero at the instant they become available.

Field Documentation

persistent_buf_alloc

void *(*) MaximumSecurityGuard::persistent_buf_alloc(size_t size, const CellOwner *owner)

Takes size bytes from the bottom for owner [RETURNS OWNERSHIP].

Definition at line 633 of file locus_carcerum.h.

persistent_buf_release

void(*) MaximumSecurityGuard::persistent_buf_release(void *prisoner, const CellOwner *owner)

Zeroes owner's cell of either tier, then releases it [TAKES OWNERSHIP].

Definition at line 635 of file locus_carcerum.h.

temporary_buf_alloc

void *(*) MaximumSecurityGuard::temporary_buf_alloc(size_t size, const CellOwner *owner)

Takes size bytes from the top for owner [RETURNS OWNERSHIP].

Definition at line 638 of file locus_carcerum.h.

who_owns_buf

embed_bool(*) MaximumSecurityGuard::who_owns_buf(const void *at)

Whether at lies in this cellblock's bytes [BORROWS].

Definition at line 640 of file locus_carcerum.h.

buf_available

size_t(*) MaximumSecurityGuard::buf_available(void)

Bytes between the two tiers.

Definition at line 641 of file locus_carcerum.h.

buf_grow

void *(*) MaximumSecurityGuard::buf_grow(void *prisoner, size_t size, const CellOwner *owner)

Grows the newest cell of its tier to size bytes in place, the added bytes zeroed.

Definition at line 642 of file locus_carcerum.h.

movable_init

embed_bool(*) MaximumSecurityGuard::movable_init(const CarcerMovableInitCfg *args)

Assigns the movable option, once.

Definition at line 645 of file locus_carcerum.h.

movable_buf_alloc

const CarcerMovableEntry *(*) MaximumSecurityGuard::movable_buf_alloc(size_t size, const CellOwner *owner)

Takes a cell a move may move: its identity, NULL where refused.

Definition at line 646 of file locus_carcerum.h.

movable_buf_release

embed_bool(*) MaximumSecurityGuard::movable_buf_release(const CarcerMovableEntry *cell, const CellOwner *owner)

Zeroes owner's movable cell, then releases it.

Definition at line 648 of file locus_carcerum.h.

movable_buf_read

embed_bool(*) MaximumSecurityGuard::movable_buf_read(const CarcerMovableCfg *args)

Copies out of a movable cell.

Definition at line 650 of file locus_carcerum.h.

movable_buf_write

embed_bool(*) MaximumSecurityGuard::movable_buf_write(const CarcerMovableCfg *args)

Copies into a movable cell.

Definition at line 651 of file locus_carcerum.h.

movable_buf_compare

embed_iword(*) MaximumSecurityGuard::movable_buf_compare(const CarcerMovableCfg *args)

Orders a movable cell's bytes.

Definition at line 652 of file locus_carcerum.h.

movable_buf_measure

size_t(*) MaximumSecurityGuard::movable_buf_measure(const CarcerMovableCfg *args)

Bytes before a movable cell's next zero.

Definition at line 653 of file locus_carcerum.h.
