void aligned_free | ( | T * | ptr | ) |
Frees memory pointed by the given pointer.
aligned_free is a wrapper for functions that free memory allocated by aligned_malloc: 'rte_free' from DPDK if hugepages are defined and 'free' otherwise.
[in] | ptr | Pointer to the allocated memory. |
Definition at line 566 of file common.hpp.
T* aligned_malloc | ( | const int | size, |
const unsigned | alignment | ||
) |
Allocates memory of the given size.
aligned_malloc is wrapper to functions that allocate memory: 'rte_malloc' from DPDK if hugepages are defined, 'memalign' otherwise. Size is defined as a number of variables of given type e.g. floats, rather than bytes. It hides sizeof(T) multiplication and cast hence makes things cleaner.
[in] | size | Size of the memory to allocate. |
[in] | alignment | Bytes alignment of the allocated memory. If 0, the return is a pointer that is suitably aligned for any kind of variable (in the same manner as malloc()). Otherwise, the return is a pointer that is a multiple of align. In this case, it must be a power of two. (Minimum alignment is the cacheline size, i.e. 64-bytes) |
