Constructor & Destructor Documentation

CaptureMemoryDelegateLinux()

crashpad::internal::CaptureMemoryDelegateLinux::CaptureMemoryDelegateLinux	(	ProcessReaderLinux *	process_reader,
		const ProcessReaderLinux::Thread *	thread_opt,
		std::vector< std::unique_ptr< MemorySnapshotGeneric > > *	snapshots,
		uint32_t *	budget_remaining )

A MemoryCaptureDelegate for Linux.

Parameters

[in]	process_reader	A ProcessReaderLinux for the target process.
[in]	thread_opt	The thread being inspected. Memory ranges overlapping this thread's stack will be ignored on the assumption that they're already captured elsewhere. May be nullptr.
[in]	snapshots	A vector of MemorySnapshotGeneric to which the captured memory will be added.
[in]	budget_remaining	If non-null, a pointer to the remaining number of bytes to capture. If this is 0, no further memory will be captured.

Member Function Documentation

AddNewMemorySnapshot()

void crashpad::internal::CaptureMemoryDelegateLinux::AddNewMemorySnapshot ( const CheckedRange< uint64_t, uint64_t > & range )

overridevirtual

Adds the given range representing a memory snapshot in the target process to the result.

Implements crashpad::internal::CaptureMemory::Delegate.

GetReadableRanges()

std::vector< CheckedRange< uint64_t > > crashpad::internal::CaptureMemoryDelegateLinux::GetReadableRanges ( const CheckedRange< uint64_t, uint64_t > & range ) const

overridevirtual

Given a range to be read from the target process, returns a vector of ranges, representing the readable portions of the original range.

Parameters

[in]

range

The range being identified.

Returns

A vector of ranges corresponding to the portion of range that is readable.

Implements crashpad::internal::CaptureMemory::Delegate.

Is64Bit()

bool crashpad::internal::CaptureMemoryDelegateLinux::Is64Bit ( ) const

overridevirtual

Returns

true if the target process is a 64-bit process.

Implements crashpad::internal::CaptureMemory::Delegate.

ReadMemory()

bool crashpad::internal::CaptureMemoryDelegateLinux::ReadMemory ( uint64_t at, uint64_t num_bytes, void * into ) const

overridevirtual

Attempts to read num_bytes bytes from the target process starting at address at into into.

Returns

true if the entire region could be read, or false with an error logged.

Implements crashpad::internal::CaptureMemory::Delegate.
