You can do something like this:

C++

int a;
float b;
double c;

#pragma omp parallel sections
{
   // Run each section in parallel
   #pragma omp section
   { a = func1(); }
   #pragma omp section
   { b = func2(); }
   #pragma omp section
   { c = func3(); }
}

// We are back in main thread, sum it up
double d = a + b + c;
