Member Function Documentation

◆ clear()

void RawUserMemory::clear ( )

Definition at line 432 of file RawUserMemory.cc.

◆ cloneInto()

MemoryLockStatus RawUserMemory::cloneInto ( RawUserMemory & target )

Definition at line 412 of file RawUserMemory.cc.

◆ completeInventory()

bool RawUserMemory::completeInventory ( ) const

Definition at line 197 of file RawUserMemory.cc.

◆ covers()

bool RawUserMemory::covers	(	uintptr_t	base,
		size_t	length
	)		const

Requires the user-memory operation gate; holes are never inferred from brk.

◆ hasLockedMemory()

bool RawUserMemory::hasLockedMemory	(	uintptr_t	base,
		size_t	length
	)		const

Definition at line 224 of file RawUserMemory.cc.

◆ nextRegionId()

uint64_t RawUserMemory::nextRegionId ( )

Definition at line 189 of file RawUserMemory.cc.

◆ prepareAllLocks()

MemoryLockStatus RawUserMemory::prepareAllLocks	(	MemoryLockMode	mode,
		UniquePointer< PreparedMemoryLock > &	result
	)

Definition at line 387 of file RawUserMemory.cc.

◆ prepareChange()

MemoryLockStatus RawUserMemory::prepareChange	(	const UserRegion *	previous,
		const UserRegion *	replacement,
		UniquePointer< PreparedMemoryLock > &	result
	)

Definition at line 235 of file RawUserMemory.cc.

◆ prepareLocks()

MemoryLockStatus RawUserMemory::prepareLocks	(	uintptr_t	base,
		size_t	length,
		MemoryLockMode	mode,
		UniquePointer< PreparedMemoryLock > &	result
	)

Definition at line 344 of file RawUserMemory.cc.

◆ prepareReplacement()

MemoryLockStatus RawUserMemory::prepareReplacement	(	uintptr_t	base,
		size_t	length,
		UniquePointer< PreparedMemoryLock > &	result
	)

Keep the user-memory operation gate through commit. Success with no raw overlap clears result and needs no commit; failures leave result unchanged.
