convert std vector to and from CniVector

[freak]

I am using the class CNiReal64Vector and need an optimized way to copy the contents of a std vector into a CniVector, and vice versa.

I am using a non-Ni library in my application and can't use Ni types throughout. Can someone point me in the right direction?

You can use memcpy().

Just to add a little more information to Mark's post, the following line of code is all that is necessary to copy elements of one vector to another:

double data[4] = {2.345, 4.567, 2.95666, 8.9222};
CNiReal64Vector cniVect(4, data);
vector stdVect(4);

memcpy(&stdVect[0], &cniVect[0], sizeof(double) * 4);

This is because the elements of both vectors are all stored contiguously in memory, and dereferencing the first item in the collection gets you the address of the first element.
