"void *(*)(void *)"是什么意思在 C++ 中是什么意思?

2021-12-13 00:00:00 pointers function-pointers c++ pthreads void-pointers

它是pthread_create()中的参数.我认为每个部分的意思是:

It's the parameter in pthread_create(). I think each part means:

  • void *:返回值是一个void指针.

  • void *: The return value is a void pointer.

(*):它是一个函数指针.

(void *):它接受一个无类型指针作为参数.

(void *): It takes an untyped pointer as a parameter.

正确吗?

推荐答案

是，它是一个无名函数指针的签名，它接受并返回void *.

Yes, it is the signature of a nameless function pointer that takes and returns void *.

如果它有一个名字(如在一个变量中)它会是:

If it had a name (as in a variable) it would be:

void *(*myFuncName)(void*)
