Member Function/Subroutine Documentation

device_memcpy_cptr()

subroutine device::device_memcpy::device_memcpy_cptr	(	type(c_ptr), intent(inout)	dst,
		type(c_ptr), intent(inout)	src,
		integer(c_size_t), intent(in)	s,
		integer, intent(in), value	dir,
		logical, optional	sync,
		type(c_ptr), optional	strm
	)

Note

For host-device copies dst is the host pointer and src is the device pointer (regardless of dir)
