## Detailed Description

This is a Standard C++ Library header.

Definition in file type_traits.

## Macro Definition Documentation

## _GLIBCXX_HAS_NESTED_TYPE

#define _GLIBCXX_HAS_NESTED_TYPE | ( |  | _NTYPE | ) |

Use SFINAE to determine if the type _Tp has a publicly-accessible member type _NTYPE.
