acc_copyout
– Copy device memory to host memory.This function copies mapped device memory to host memory which is specified by host address a for a length len bytes in C/C++.
In Fortran, two (2) forms are supported. In the first form, a specifies a contiguous array section. The second form a specifies a variable or array element and len specifies the length in bytes.
