Compiler Error C3201

the template parameter list for class template 'template' does not match the template parameter list for template parameter 'template'

Remarks

You passed a class template in the argument to a class template that does not take a template parameter, or you passed a mismatched number of template arguments for the default template argument.

Example

The following example generates C3201:

// C3201.cpp
template<typename T1, typename T2>
class X1
{
};

template<template<typename T> class U = X1>   // C3201
class X2
{
};

template<template<typename T, typename V> class U = X1>   // OK
class X3
{
};
