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.
