[edit] Parameters
(none)
[edit] Return value
A description of the represented evaluation on success, an empty string on failure other than allocation failure.
[edit] Exceptions
Throws std::bad_alloc if memory for the internal data structures or the resulting string cannot be allocated.
[edit] Notes
Custom allocators support for this function is not provided, because the implementations usually require platform specific allocations, system calls and a lot of CPU intensive work, while a custom allocator does not provide benefits for this function as the platform specific operations take an order of magnitude more time than the allocation.
