Hi everybody,

I have a small problem here... I need to copy the contents of a vector to a certain position in an array. However, memcpy returns the error "invalid conversion from int to void*"
Here's an example of what I'm trying to do:

QVector<qint16> Vector1(1024);
QVector<qint16> Vector2(1024);
QVector<qint16> Vector3(1024);

int HArr[1024][1024];

memcpy(HArr[0][0], &Vector1[0], 1024);
memcpy(HArr[0][1], &Vector2[0], 1024);
memcpy(HArr[0][2], &Vector3[0], 1024);

Can someone show me how to do this correctly ?

Thanks,
Peter
