WINBIO_DATA structure (winbio_ioctl.h)

The WINBIO_DATA structure specifies data in IOCTL payloads.

Syntax

typedef struct _WINBIO_DATA {
  DWORD Size;
  BYTE  Data[1];
} WINBIO_DATA, *PWINBIO_DATA;

Members

Size

Specifies the size, in bytes, of the payload.

Data[1]

Specifies an array that contains the payload. Frequently this member contains a structure of type WINBIO_BIR.

Remarks

The WINBIO_DATA structure associates a length, in bytes, with an arbitrary block of contiguous memory.
