Passing arguments to pthread function
In this example, we want to pass more than one argument to the function, so we create a pointer point to a struct we have created, transfer it into (void *) and pass to function. In function, we transfer the type of pointer to the real type, so that we can properly use it.

Default arguments
 · If a non-inline function is declared in the same namespace scope in different translation units, the corresponding default arguments must be the same if present (but some default arguments can be absent in some TU). If a friend declaration specifies a default, it must be a friend function definition, and no other declarations of this function are allowed in the translation unit.

Argument Handling
In this case, you can see how the output value normally returned in the third argument has magically been transformed into a function return value. Clearly this makes the function much easier to use since it is no longer necessary to manufacture a special double * object and pass it to the function somehow.
