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.

struct std::nothrow_t {};

Remarks

The struct helps the compiler to select the correct version of the constructor. nothrow (<new>) 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.
