BIDI_DATA structure (winspool.h)

The BIDI_DATA structure is used to store the values of a bidi schema.

Syntax

typedef struct _BIDI_DATA {
  DWORD dwBidiType;
  union {
    BOOL             bData;
    LONG             iData;
    LPWSTR           sData;
    FLOAT            fData;
    BINARY_CONTAINER biData;
  } u;
} BIDI_DATA, *PBIDI_DATA, *LPBIDI_DATA;

Members

dwBidiType

Specifies the type of data in a bidi request as one of the values listed in the BIDI_TYPE enumeration. The value of this member determines which one of the following five union members is valid.

u

u.bData

Specifies the Boolean value. This member is valid only if the value of dwBidiType is BIDI_BOOL, one of the BIDI_TYPE enumerators.

u.iData

Specifies the integer value. This member is valid only if the value of dwBidiType is BIDI_INT, one of the BIDI_TYPE enumerators.

u.sData

Pointer to a memory location at which the first byte of the string is stored. This member is valid only if the value of dwBidiType is BIDI_STRING or BIDI_TEXT, two of the BIDI_TYPE enumerators.

u.fData

Specifies the floating-point value. This member is valid only if the value of dwBidiType is BIDI_FLOAT, one of the BIDI_TYPE enumerators.

u.biData

Specifies a BINARY_CONTAINER structure that holds the binary data. This member is valid only if the value of dwBidiType is BIDI_BLOB, one of the BIDI_TYPE enumerators.

Remarks

The BIDI_REQUEST_DATA and BIDI_RESPONSE_DATA structures each have a member of this type, which holds the bidi data for the request or response.
