Definition: aligned_memory.hpp:83
foedus::memory::AlignedMemory::alloc
void alloc(uint64_t size, uint64_t alignment, AllocType alloc_type, int numa_node) noexcept
Allocate a memory, releasing the current memory if exists.
Definition: aligned_memory.cpp:113
foedus::memory::AlignedMemory::get_block
void * get_block() const
Returns the memory block.
Definition: aligned_memory.hpp:168
foedus::memory::AlignedMemory::get_size
uint64_t get_size() const
Returns the byte size of the memory block.
Definition: aligned_memory.hpp:172
foedus::kRetOk
const ErrorStack kRetOk
Normal return value for no-error case.
Definition: error_stack.hpp:251
WRAP_ERROR_CODE
#define WRAP_ERROR_CODE(x)
Same as CHECK_ERROR(x) except it receives only an error code, thus more efficient.
Definition: error_stack.hpp:533
foedus::memory::AlignedMemory::is_null
bool is_null() const
Returns if this object doesn't hold a valid memory block.
