Если выделение успешно, возвращает указатель на самой низкой (первой) байт в выделенный блок памяти, который соответствующим выровнены для любого типа объектов.
Original:
If allocation succeeds, returns a pointer to the lowest (first) byte in the allocated memory block that is suitably aligned for any object type.

Если size равна нулю, то поведение определяется реализацией (нулевого указателя могут быть возвращены, или некоторые не нулевой указатель может быть возвращен, которая не может быть использован для доступа к памяти)
Original:
If size is zero, the behavior is implementation defined (null pointer may be returned, or some non-null pointer may be returned that may not be used to access storage)

[править] Notes

Эта функция не вызывать конструкторы или инициализации памяти в любом случае. Таким образом, предпочтительный способ распределения памяти является new выражение.
Original:
This function does not call constructors or initialize memory in any way. Thus preferred method of memory allocation is new expression.
