它是sizeof（void *）...

它可能是sizeof（void *）== sizeof（long），但它可能不一样。

任何依赖于上述条件的东西都被认为是不便携的。

它是sizeof（void *）

指向void的指针与指向char的指针大小相同。


指向结构的指针大小相同。


大多数其他类型指针的大小

没有特殊规格。

It is sizeof(void*)...
It may be sizeof(void*)==sizeof(long), but it may not be as well.
Whatever depends on the conditional above is considered not portable.

It is sizeof(void*)

Pointers to void are the same size as pointers to char.

Pointers to structures are the same size as each other.

The sizes of most other types of pointers
have no special specifications.
