pointers - What does "void *(*)(void *)" mean in C++?

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

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

  • (*): It's a pointer to a function.

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

Is that correct?

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

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

void *(*myFuncName)(void*)
