Member Function Documentation

allocate()

LIBCOPP_COPP_API void allocator::stack_allocator_memory::allocate	(	stack_context &	ctx,
		std::size_t	size
	)

allocate memory and attach to stack context [standard function]

Parameters

ctx	stack context
size	stack size

Note

size must less or equal than attached

Definition at line 93 of file stack_allocator_memory.cpp.

		std::size_t	max_size
	)

specify memory section allocated

Parameters

start_ptr	buffer start address
max_size	buffer size

Note

must be called before allocate operation
