发帖数: 3557 | 9 In case of a function template, template argument deduction is performed
before the compiler tries to resolve the overloading [13.3.1 paragraph 7].
In other words, the compiler sees "a*b", then it looks for all overloaded "
operator*". You have "template operator *(const A&, const A&)
;" defined up there, so it tries to deduct the typename T. Note that the
compiler doesn't look into anything else in this step, including your user-

Note that there is a problem with this example: addValue is a
function template, and function templates are considered to name a set of
overloaded functions (even if the set has only one member). However,
according to the current standard, sets of overloaded functions cannot be
used for template parameter deduction. Thus, you have to cast to the exact
type of the function template argument: |

Only user defined class can have overloaded operator. The compiler will try
to resolve the operator based on the type of the operand. If you have two
classes of the same name but in different namespace, then you need to
specify which class the object is when it is declared. I don't see how you
can overload an operator with the same signature unless you do it on purpose.
Also related is the special "Koenig lookup".

发帖数: 5393 | 17 可以分开啊，比如：

write(parameter);
}
int main()
{
test(1);
test("adbsdfs");
return 1;
}
template
void write(T a)
{
std::cout<
}
关键是compiler在instantialize你的template的时候，会好像#define一样展开，你的
code里面的两个Read（一个declare,一个definition），展开后是不同的两个东西，所
以当然会说第一个Read找不到definition了。

除非node都有load，才会有多个thread在同一个node，个人感觉只有node overload之

thread跳动的cost。系统cpu的load均衡不均衡不是很重要，除非都utilized了，然后
