I am trying to create a template for a
multi-parameter function, and then an alias for a particular instantiation. From this
really good post:
href="https://stackoverflow.com/questions/9864125/c11-how-to-alias-a-function">C++11:
How to alias a function?
I
found example code that works for a single function parameter and single template
parameter:
#include
namespace Bar
{
void test()
{
std::cout << "Test\n";
}
template
void test2(T const& a)
{
std::cout << "Test: " << a << std::endl;
}
}
void (&alias)() = Bar::test;
void
(&a2)(int const&) = Bar::test2;
int
main()
{
Bar::test();
alias();
a2(3);
}
When
I try to expand to two function parameters as
such:
void noBarTest(T
const& a, T const& b)
{
std::cout << "noBarTest: "
<< a << std::endl;
}
void(&hh)(int
const&, int const&) = noBarTest int>;
I get these
errors in Visual
Studio:
error C2440: 'initializing' : cannot convert from 'void (__cdecl
*)(const T &,const T &)' to 'void (__cdecl &)(const int &,const int
&)'
IntelliSense: a reference of type
"void (&)(const int &, const int &)"
(not const-qualified) cannot
be initialized with a value of type
""
I
thought I followed the pattern exactly in expanding to 2 arguments.
What's
the proper syntax for this?
