unsafe_copy!(dest::Array, d, src::Array, so,

unsafe_copy!(dest::Array, do, src::Array, so, N)

Copy N elements from a source array to a destination, starting at offset so in the source and do in the destination (1-indexed).

The unsafe prefix on this function indicates that no validation is performed to ensure that N is inbounds on either array. Incorrect usage may corrupt or segfault your program, in the same manner as C.

Examples

Unsafe copy of elements from one array to another:
```
julia> src = [1, 2, 3, 4, 5];
julia> dest = zeros(Int, 5);
julia> unsafe_copy!(dest, 1, src, 1, 5)
5-element Array{Int64,1}:
1
2
3
4
5
```
This example performs an unsafe copy of all elements from the source array src to the destination array dest.
Copying a subset of elements using offsets:
```
julia> src = [10, 20, 30, 40, 50];
julia> dest = zeros(Int, 3);
julia> unsafe_copy!(dest, 1, src, 2, 3)
3-element Array{Int64,1}:
20
30
40
```
In this example, the unsafe copy is performed starting from the second element of the source array (src) and copied to the destination array (dest) starting from the first index.
Unsafe copy with overlapping arrays:
```
julia> src = [1, 2, 3, 4, 5];
julia> dest = [10, 20, 30, 40, 50];
julia> unsafe_copy!(dest, 3, src, 2, 4)
5-element Array{Int64,1}:
10
20
 2
 3
 4
```
This example demonstrates an unsafe copy where the copied elements overlap with the existing elements in the destination array.

Note: It is important to exercise caution while using unsafe_copy! as no bounds checking is performed. Incorrect usage may lead to memory corruption or program crashes.
