Function Documentation

template<class T , class A >
A::pointer StandardReallocate ( A &  alloc,
T *  oldPtr,
typename A::size_type  oldSize,
typename A::size_type  newSize,
bool  preserve 
) [inline]

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.
