How to check the results of new (memory allocation)

I was trying to figure out if there is a portable method for finding out if using "new" succeeded. For example:

int* temp = new int[5000];

If the memory is not allocated for any reason, how can I find out, so I may free some memory up.

Thanx.

straight from the help source...

Handling Errors for the new Operator

You can define a function to be called if the new operator fails. To tell the new operator about the new-handler function, use set_new_handler and supply a pointer to the new-handler. If you want new to return null on failure, you must use set_new_handler(0).

i got this from bc45's help, and i would assume it's portable, but i wouldn't know for sure...

The new statement returns a pointer to the allocated location (if it succeeded)
I'd say just check for null (but check the compiler docs) That's pretty easy.
a bad_alloc exception may be thrown by some compilers.

Code:

---

int *ptr;
ptr = new int[size];

if( null == ptr )
 // memory allocation failure
