The contents and meaning of the header `<cstdlib>` are the same as the C
|
| 95 |
+
standard library header `<stdlib.h>`, except that it does not declare
|
| 96 |
+
the type `wchar_t`, and except as noted in [[support.types.nullptr]],
|
| 97 |
+
[[support.types.layout]], [[support.start.term]], [[c.malloc]],
|
| 98 |
+
[[c.mb.wcs]], [[alg.c.library]], [[c.math.rand]], and [[c.math.abs]].

[*Note 1*: Several functions have additional overloads in this
|
| 101 |
+
International Standard, but they have the same behavior as in the C
|
| 102 |
+
standard library ([[library.c]]). — *end note*]
