Member Function Documentation

allocated()

size_t CppCommon::NullMemoryManager::allocated ( ) const

inlinenoexcept

Allocated memory in bytes.

Definition at line 35 of file allocator_null.h.

allocations()

size_t CppCommon::NullMemoryManager::allocations ( ) const

inlinenoexcept

Parameters

size	- Block size
alignment	- Block alignment (default is alignof(std::max_align_t))

Returns

A pointer to the allocated memory block or nullptr in case of allocation failed

Definition at line 11 of file allocator_null.inl.
