[edit]

constchar* name()constnoexcept;		(since C++11)

Returns the name of the associatedstd::type_info object. Equivalent to callingstd::type_info::name() directly.

[edit]Parameters

(none)

[edit]Return value

The name of the associatedstd::type_info object.

[edit]Example

Run this code

#include <iostream>#include <typeindex>int main(){std::cout<<std::type_index(typeid(std::cout)).name();}

Possible output:

NSt3__113basic_ostreamIcNS_11char_traitsIcEEEE
