Member Function Documentation

Address()

uint64_t crashpad::internal::MemorySnapshotMinidump::Address ( ) const

overridevirtual

The base address of the memory snapshot in the snapshot process’ address space.

Implements crashpad::MemorySnapshot.

Initialize()

bool crashpad::internal::MemorySnapshotMinidump::Initialize	(	FileReaderInterface *	file_reader,
		RVA	location )

Initializes the object.

Parameters

[in]	file_reader	A file reader corresponding to a minidump file. The file reader must support seeking.
[in]	location	The location within the file where we will find a MINIDUMP_MEMORY_DESCRIPTOR from which to initialize this object.

Returns

true if the snapshot could be created, false otherwise with an appropriate message logged.

MergeWithOtherSnapshot()

const MemorySnapshot * crashpad::internal::MemorySnapshotMinidump::MergeWithOtherSnapshot ( const MemorySnapshot * other ) const

overridevirtual

Creates a new MemorySnapshot based on merging this one with other.

The ranges described by the two snapshots must either overlap or abut, and must be of the same concrete type.

Returns

A newly allocated MemorySnapshot representing the merged range, or nullptr with an error logged.

Implements crashpad::MemorySnapshot.

Read()

bool crashpad::internal::MemorySnapshotMinidump::Read ( Delegate * delegate ) const

overridevirtual

Calls Delegate::MemorySnapshotDelegateRead(), providing it with the memory snapshot’s data.

Implementations do not necessarily read the memory snapshot data prior to this method being called. Memory snapshot data may be loaded lazily and may be discarded after being passed to the delegate. This provides clean memory management without burdening a snapshot implementation with the requirement that it track all memory region data simultaneously.

Returns

false on failure, otherwise, the return value of Delegate::MemorySnapshotDelegateRead(), which should be true on success and false on failure.

Implements crashpad::MemorySnapshot.

Size()

size_t crashpad::internal::MemorySnapshotMinidump::Size ( ) const

overridevirtual

The size of the memory snapshot.

Implements crashpad::MemorySnapshot.
