Detailed Description

The minimum security guard over one cellblock: a released cell keeps whatever is in it.

Note

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

Every entry is bound to the cellblock its declaration named. No call carries a cellblock argument and there is nothing to pass wrongly. A cellblock at this level has no zeroing release. The difference between the two levels is what exists, not what a caller remembers to reach for.

A cell of either tier is given back the same way, through persistent_buf_release, which reads the tier off the cell's offset.

Field Documentation

persistent_buf_alloc

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

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

Definition at line 595 of file locus_carcerum.h.

persistent_buf_release

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

Releases owner's prisoner of either tier, cell left as it is [TAKES OWNERSHIP].

Definition at line 598 of file locus_carcerum.h.

temporary_buf_alloc

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

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

Definition at line 601 of file locus_carcerum.h.

who_owns_buf

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

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

Definition at line 604 of file locus_carcerum.h.

buf_available

size_t(*) MinimumSecurityGuard::buf_available(void)

Bytes between the two tiers.

Definition at line 605 of file locus_carcerum.h.

buf_grow

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

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

Definition at line 606 of file locus_carcerum.h.

movable_init

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

Definition at line 609 of file locus_carcerum.h.

movable_buf_alloc

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

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

Definition at line 610 of file locus_carcerum.h.

movable_buf_release

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

Copies out of a movable cell.

Definition at line 614 of file locus_carcerum.h.

movable_buf_write

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

Copies into a movable cell.

Definition at line 615 of file locus_carcerum.h.

movable_buf_compare

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

Orders a movable cell's bytes.

Definition at line 616 of file locus_carcerum.h.

movable_buf_measure

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

Bytes before a movable cell's next zero.
