1 5.23 'acc_update_device' - Update device memory from mapped host memory.
1 ========================================================================

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