3
- Header `<cstdlib>` ([[cstdlib.syn]]): The following functions have
4
- different behavior:
5
 
6
  - `atexit`
7
  - `exit`
8
  - `abort`
9
 
10
  Subclause [[support.start.term]] describes the changes.

12
- Header `<csetjmp>` ([[csetjmp.syn]]): The following functions have
13
- different behavior:
14
 
15
  - `longjmp`
16
 
17
  Subclause [[csetjmp.syn]] describes the changes.

  #### Macro `offsetof(type, member-designator)` <a id="diff.offsetof">[[diff.offsetof]]</a>
20
 
21
- The macro `offsetof`, defined in `<cstddef>` ([[cstddef.syn]]), accepts
22
- a restricted set of `type` arguments in this International Standard.
23
- Subclause [[support.types.layout]] describes the change.
24
 
25
  #### Memory allocation functions <a id="diff.malloc">[[diff.malloc]]</a>
26
 
27
  The functions `aligned_alloc`, `calloc`, `malloc`, and `realloc` are
