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.
