# std::\_Reference\_wrapper\_base(3cxx)

## NAME

std::\_Reference\_wrapper\_base\< \_Tp \>

## SYNOPSIS

Inherits **std::\_Weak\_result\_type\< \_Tp \>**, std::\_Refwrap\_base\_arg1\< \_Tp, typename \>, and std::\_Refwrap\_base\_arg2\< \_Tp, typename \>.

Inherited by std::\_Reference\_wrapper\_base\_memfun\< remove\_cv\< \_Tp \>::type \>, and std::\_Reference\_wrapper\_base\_memfun\< \_Tp, bool \>.

## Detailed Description

### template\<typename \_Tp\>

struct std::\_Reference\_wrapper\_base\< \_Tp \>" Derives from unary\_function or binary\_function when it can. Specializations handle all of the easy cases. The primary template determines what to do with a class type, which may derive from both unary\_function and binary\_function.
