Buffer::Copy

This method copies the contents of this buffer to another one.

Syntax

void Copy(const uint64_t srcoffset, shared_ptr<Buffer> dst, const uint64_t dstoffset, const uint64_t size)

Parameter	Description
srcoffset	offset for the source buffer data, in bytes
dst	destination buffer
dstoffset	offset for the destination buffer data, in bytes
size	number of bytes to copy

Remarks

A runtime error will occur if the source or destination range lies outside of the buffer extents.

Example

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Create two buffers
    array<int, 10> arr = { 0,1,2,3,4,5,6,7,8,9 };
    auto buffer1 = CreateStaticBuffer(arr.data(), arr.size() * sizeof(int));
    auto buffer2 = CreateBuffer(4 * sizeof(int));

    //Copy part of the buffer contents
    buffer1->Copy(3 * sizeof(int), buffer2, 0, buffer2->GetSize());

    //DIsplay the copied contents
    for (int n = 0; n < 4; ++n)
    {
        Print(buffer2->PeekInt(n * sizeof(int)));
    }

    return 0;
}
