add_ref(Ref, Pid) -> any()
alloc(Id::segment_id(), Size::integer(), Pid::pid()) -> {segment_id(), Offset::integer()}
Allocate data.
Preferably from segment idId, if possible. This will rarely
fail, as new segments are added in case there is not enough free
space left.
code_change(OldVsn, State, Extra) -> any()
discard_ref(Ref, Pid) -> any()
get_cap(Idx, Pid) -> any()
get_cap_idx(Cap, Pid) -> any()
get_cap_table(Pid) -> any()
get_segment(Id::segment_id(), Offset::integer(), Length::integer(), Pid::pid()) -> binary()
Read data from segment.
get_segment_size(Id::segment_id(), Pid::pid()) -> integer()
Get size of segment, in words (8 bytes).
get_segments(Pid::pid()) -> [binary()]
Get all allocated data from all segments.
handle_call(X1, From, State) -> any()
handle_cast(X1, State) -> any()
handle_info(Info, State) -> any()
init(X1) -> any()
set_cap_table(CapTable, Pid) -> any()
start(Init) -> any()
start_link(Init) -> any()
stop(Pid) -> any()
terminate(Reason, State) -> any()
update_segment(X1::{segment_id(), integer()}, Data::binary(), Pid::pid()) -> ok
Write data to segment.
