*是c ++函数名？

Question

While browsing the Genode source code documentation, I came across a function who's name started with an asterisk (*), specifically,

Hello::Session_component *_create_session(const char *args)

I typically work in C, not C++ so am a little confused by this. Is this a pointer to a function named _create_session(), is the * part of the function name, or something else completely?

You can find the code example here .

Answer 1

The function is named _create_session, and its return type is a pointer to a Hello::Session_component.

This works just as it does in C:

T *func();  // return type is T*
T* func();  // exact same declaration

Answer 2

*表示返回类型而不是方法名称，在这种情况下它返回Hello::Session_component* ，因此指向Session_component的指针。
