This function copies data from device memory that was mapped during initialization with the NdisMMapIoSpace function to a system-space buffer.
VOID NdisMoveFromMappedMemory(PVOIDDestination,PVOIDSource,ULONGLength);
Parameters
- Destination
[out] Pointer to a system-space buffer into which this function copies data from mapped device memory. This buffer must be at least Length bytes in size. - Source
[in] Specifies the base virtual address within mapped device memory from which to copy the data. This address must fall at least Length bytes from the end of the mapped range. - Length
[in] Specifies the number of bytes to copy.
Return Values
None.
Remarks
An NIC driver calls this function to copy data from NIC memory into a buffer in the host, as, for example, when transferring received data into a protocol-supplied buffer or miniport-allocated staging buffer.
Both the Source and Destination pointers are virtual addresses. The virtual range specified by Source and Length must fall within a range of device memory that was mapped during initialization with the NdisMMapIoSpace function.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Ndis.h.
Link Library: Ndis.dll.
