document difference between std::copy and thrust::copy #173

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Namely, thrust::copy cannot be used to copy overlapping ranges such as
int A[10];
A[0..8] <- A[1..9];

In contrast, std::copy does permit overlapping ranges [1].  Similarly, 
std::copy_backward allows the result range to overlap on the right.
