Data Alignment

The following C run-time functions support data alignment.

Data-Alignment Routines

Routine	Use	.NET Framework equivalent
_aligned_free	Frees a block of memory that was allocated with _aligned_mallocor _aligned_offset_malloc.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_free_dbg	Frees a block of memory that was allocated with _aligned_malloc or _aligned_offset_malloc (debug only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_malloc	Allocates memory on a specified alignment boundary.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_malloc_dbg	Allocates memory on a specified alignment boundary with additional space for a debugging header and overwrite buffers (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_msize	Returns the size of a memory block allocated in the heap.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_msize_dbg	Returns the size of a memory block allocated in the heap (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_offset_malloc	Allocates memory on a specified alignment boundary.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_offset_malloc_dbg	Allocates memory on a specified alignment boundary (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_offset_realloc	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_offset_realloc_dbg	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_offset_recalloc	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc and initializes the memory to 0.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_offset_recalloc_dbg	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc and initializes the memory to 0 (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_realloc	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_realloc_dbg	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_recalloc	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc and initializes the memory to 0.	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
_aligned_recalloc_dbg	Changes the size of a memory block that was allocated with _aligned_malloc or _aligned_offset_malloc and initializes the memory to 0 (debug version only).	Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
