class Snapshot

Defined at line 64 of file ../../zircon/system/ulib/inspect/include/lib/inspect/cpp/vmo/snapshot.h

|Snapshot| parses an incoming VMO buffer and produces a snapshot of the VMO contents. |Snapshot::Options| determines the behavior of snapshotting if a concurrent write potentially occurred.

Example: Snapshot* snapshot; zx_status_t status = Snapshot::Create(std::move(vmo), {.read_attempts = 1024, .skip_consistency_check = false},&snapshot);

Test Example: zx_status_t status = Snapshot::Create(std::move(vmo), {.read_attempts = 1024, .skip_consistency_check = false}, std::make_unique<TestCallback>(),&snapshot);

Create

public zx_status_t Create(const zx::vmo & vmo, Options options, Snapshot * out_snapshot)

Defined at line 59 of file ../../zircon/system/ulib/inspect/vmo/snapshot.cc

Create a new snapshot of the given VMO using the given options.

Create

public zx_status_t Create(const zx::vmo & vmo, Options options, ReadObserver read_observer, Snapshot * out_snapshot)

Defined at line 63 of file ../../zircon/system/ulib/inspect/vmo/snapshot.cc

Create

public zx_status_t Create(BackingBuffer && buffer, Snapshot * out_snapshot)

Defined at line 33 of file ../../zircon/system/ulib/inspect/vmo/snapshot.cc

Create a new snapshot over the supplied buffer. If the buffer cannot be interpreted as a snapshot, an error status is returned. There are no observers or writers involved.
