__attribute__()

__attribute__

(

(visibility("default"))

)

const = NULL)

Function to handle runtime errors.

Portable swap code.

Portable memory placement helper function.

Portable memory allocation helper function.

When using the standard C library, runtime errors are handled by a simple abort. When using the stdc++ library with stdexcept, then std::runtime_error will be thrown.

Parameters

text	of runtime error.

Handles out of heap error as a runtime error.

Parameters

size	of memory block to allocate from heap.

Returns

memory address of allocated heap space.

This is used to process "placement" new operators where a new object is constructed over a pre-allocated area of memory. This handles invalid values through runtime error.

Parameters

size	of object being constructed.
address	where the object is being placed.
known	size of the location we are constructing the object in.
mem1	to swap.
mem2	to swap.
size	of swap area.
