nothrow_t Structure
The latest version of this topic can be found at nothrow_t Structure.
The struct is used as a function parameter to operator new to indicate that the function should return a null pointer to report an allocation failure, rather than throw an exception.
Syntax
struct std::nothrow_t {};
Remarks
The struct helps the compiler to select the correct version of the constructor. nothrow is a synonym for objects of type std::nothrow_t.
Example
See operator new and operator new[] for examples of how std::nothrow_t is used as a function parameter.
