Buffer::PeekDouble

This method returns a double float value from the memory buffer.

Syntax

• double PeekDouble(const uint64_t pos)

Parameters

Returns

Returns a double float value.

Remarks

A runtime error will occur if the read range lies outside of the buffer extents. Note that a double value is 8 bytes, twice the size of an int or float value.

Example

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Create a buffer
    auto buffer = CreateBuffer(20 * sizeof(double));

    //Poke data to the buffer
    for (int n = 0; n < buffer->GetSize() / sizeof(double); ++n)
    {
        buffer->PokeDouble(n * sizeof(double), n + 1);
    }

    //Peek and display data from the buffer
    for (int n = 0; n < buffer->GetSize() / sizeof(double); ++n)
    {
        Print(buffer->PeekDouble(n * sizeof(double)));
    }

    return 0;
}
