Function Documentation

StandardReallocate()

template<class T , class A >

A::pointer StandardReallocate	(	A &	alloc,
		T *	oldPtr,
		typename A::size_type	oldSize,
		typename A::size_type	newSize,
		bool	preserve
	)

Reallocation function.

Template Parameters

T	the class or type
A	the class or type's allocator

Parameters

alloc	the allocator
oldPtr	the previous allocation
oldSize	the size of the previous allocation
newSize	the new, requested size
preserve	flag that indicates if the old allocation should be preserved

Note

oldSize and newSize are the count of elements, and not the number of bytes.
