Member Function Documentation

AllocateLocked()

void * TestLockedPageAllocator::AllocateLocked ( size_t  len, bool *  lockingSuccess  )

inlineoverridevirtual

Allocate and lock memory pages.

If len is not a multiple of the system page size, it is rounded up. Returns nullptr in case of allocation failure.

If locking the memory pages could not be accomplished it will still return the memory, however the lockingSuccess flag will be false. lockingSuccess is undefined if the allocation fails.

Implements LockedPageAllocator.

Definition at line 139 of file allocator_tests.cpp.

FreeLocked()

void TestLockedPageAllocator::FreeLocked ( void *  addr, size_t  len  )

inlineoverridevirtual

Unlock and free memory pages.

Clear the memory before unlocking.

Implements LockedPageAllocator.

Definition at line 154 of file allocator_tests.cpp.

GetLimit()

size_t TestLockedPageAllocator::GetLimit ( )

inlineoverridevirtual

Get the total limit on the amount of memory that may be locked by this process, in bytes.

Return size_t max if there is no limit or the limit is unknown. Return 0 if no memory can be locked at all.

Implements LockedPageAllocator.
