Is it possible to store 2 32-bit values in one long int variable?

Question

I want to store two 32-bit values in a single long int variable.

How would you do this on a 32-bit OS using C? Is it possible to store the data in a single long long

Answer 1

Assuming a long is 64 bits on your platform,

int v1 = 123;
int v2 = 456;
long val = v1 << 32 | v2;
