_NDK_LOGICAL_ADDRESS_MAPPING structure

Description

The NDK_LOGICAL_ADDRESS_MAPPING structure contains an array of adapter logical addresses.

Members

`AdapterContext`

Reserved for the NDK provider's use. The NDK consumer must not modify this member.

`AdapterPageCount`

The number of entries in the array that is specified in the AdapterPageArray member.

`AdapterPageArray`

An array of adapter logical addresses. Each logical address in the array corresponds to a page, of PAGE_SIZE bytes in length, and must be PAGE_SIZE-aligned. The array of pages correspond to a virtually contiguous memory region. The NDK_LOGICAL_ADDRESS datatype is defined as follows:

typedef PHYSICAL_ADDRESS NDK_LOGICAL_ADDRESS;

Remarks

NDK_LOGICAL_ADDRESS_MAPPING represents an adapter's view of physical memory. See NDK_FN_BUILD_LAM and NDK_FN_RELEASE_LAM for more information.
