我正在尝试使用boost scope_guard
我需要将成员函数的函数指针发送到make_guard函数
我按照以下方式尝试了它:
class A
{
HRESULT foo(int x);
HRESULT foo_1(int x);
}
STDMETHODIMP A::foo(int x)
{....};
STDMETHODIMP A::foo_1(int x)
{
boost::scope_guard xyz=
boost::make_guard(&A::foo, x);
}
但它会出现编译错误:
E:\ThirdPartyCore\Boost\1_43_0\winx64\include\boost/multi_index/detail/scope_guard.hpp(103) : error C2064: term does not evaluate to a function taking 1 arguments

with

任何人都可以帮我修理它。

与错误消息一样,A::foo
不是一个带一个参数的函数;它是一个成员函数。我相信你想使用obj_scope_guard
和make_obj_scope_guard
,传递this
。
