_callnewh
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.
