c++ - How to write "target data map" for std::vector in OpenMP 4? -

-

i want use c++ , vectors. had c code c arrays created this:

double* data = (double*)malloc(sizeof(double) * n); double* result = (double*)malloc(sizeof(double) * n);  #pragma omp target data map(tofrom: data[0:n],result[0:n]) //loop

now use c++ vector , get:

example.cpp:31:41: error: expected variable name or array item     #pragma omp target data map(tofrom: data[0:n],result[0:n])

here openmp4 introduced user-defined reductions. have analogs data maps?

you pointers of underlying storage of std::vector , use them in same way in c code. 

double* data = vec_data.data(); double* result = vec_res.data(); int n = vec_data.size();  #pragma omp target data map(tofrom:data[0:n],result[0:n]) //loop
