MoveIn64(AddressSpace,Int64,Int64) Method



The address space.
The offset (in bytes) of the address or register from which bytes are moved.
The number of elements to transfer.
[Register-Based] Moves a 64-bit block of data from the specified memory space (assigned memory base + offset) to local memory.
Syntax
'Declaration
 
Public Overloads Function MoveIn64( _
   ByVal space As AddressSpace, _
   ByVal sourceOffset As Long, _
   ByVal count As Long _
) As Long()
'Usage
 
Dim instance As VxiSession
Dim space As AddressSpace
Dim sourceOffset As Long
Dim count As Long
Dim value() As Long
 
value = instance.MoveIn64(space, sourceOffset, count)

Parameters

space
The address space.
sourceOffset
The offset (in bytes) of the address or register from which bytes are moved.
count
The number of elements to transfer.

Return Value

The data read from the bus.
Remarks

If the session is an instrument (INSTR) session, the offset parameter specifies a relative offset from the start of the instrument’s address space. If the session is a memory access (MEMACC) session, the offset parameter is an absolute offset from the start of memory in the specified address space.

All operations on a PXI memory access session that accept a space parameter to indicate the address space for bus access will accept the value AddressSpace.PxiAllocation.

The count parameter is the number of 64-bit elements to transfer, beginning at the specified offset. Therefore, (offset + count*8) cannot exceed the amount of memory exported by the device in the given space.

Requirements

Current with Keysight IO Libraries Suite 18
