It may mean something different and this is sort of just stupid re-use of syntax although frankly it wouldn't really be much fun to have yet a symbol so they went with the same symbol which is pretty reasonable in the context *a of a function prototype this just means *a expect A to be the address of an int and expect B to be the address of an int.

这里的意思有点不同,这是为了重使用的目的,虽然这个符号没有什么意义,所以在函数原型中，他们就使用了相同的符号,这只是表示，期望,是一个int型的地址,期望b是一个int型的地址。
