  • Article

Contains parameters for the Identify command that returns a data buffer that describes information about the NVM subsystem, the controller or the namespace(s).

The NVME_CDW10_IDENTIFY structure is used in the CDW10 field of the IDENTIFY parameter in the Command structure.

Syntax

typedef union {
  struct {
    ULONG CNS : 8;
    ULONG Reserved : 8;
    ULONG CNTID : 16;
  } DUMMYSTRUCTNAME;
  ULONG  AsUlong;
} NVME_CDW10_IDENTIFY, *PNVME_CDW10_IDENTIFY;
