Calls the currently installed new handler.

Syntax

int _callnewh(
   size_t size
   )

Parameters

size
The amount of memory that the new operator tried to allocate.

Return value

Value	Description
0	Failure: Either no `new` handler is installed or no `new` handler is active.
1	Success: The `new` handler is installed and active. The memory allocation can be retried.

Exceptions

This function throws bad_alloc if the new handler can't be located.

Remarks

The new handler is called if the new operator fails to successfully allocate memory. The new handler might then initiate some appropriate action, such as freeing memory so that subsequent allocations succeed.

By default, this function's global state is scoped to the application. To change this behavior, see Global state in the CRT.
