  [in]  NDK_PD *pNdkPd,
  [out] UINT32 *pToken
)
{...}

Parameters

[in] pNdkPd

A pointer to an NDK protection domain (PD) object (NDK_PD).

[out] pToken

Remarks

NdkGetPrivilegedMemoryRegionToken gets a privileged memory region token value that allows adapter logical addresses to be used directly without memory registration. This token must provide LOCAL_READ and LOCAL_WRITE access. A provider must never allow remote access for the privileged memory region token.
