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.
