1 _Description_
1      This function updates the host copy from the previously mapped
1      device memory.  The host memory is specified with the host address
1      A and a length of LEN bytes.

1      In Fortran, two (2) forms are supported.  In the first form, A
1      specifies a contiguous array section.  The second form A specifies
1      a variable or array element and LEN specifies the length in bytes.
