HV_MESSAGE_FLAGS union
The HV_MESSAGE_FLAGS union describes flags that modify the behavior of a message.
Syntax
typedef union _HV_MESSAGE_FLAGS { UINT8 AsUINT8; struct { UINT8 MessagePending :1; UINT8 Reserved :7; }; } HV_MESSAGE_FLAGS, *PHV_MESSAGE_FLAGS;
Members
- AsUINT8
-
A member in the union that can hold one 8-bit value that describes modification behavior for a message.
- MessagePending
-
A UINT8 value that indicates whether the message is pending. Setting this member is equivalent to setting the first bit of the 8-bit AsUINT8 member (0x01).
- Reserved
-
This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining seven bits (0xFE) of the 8-bit AsUINT8 member to zeros.
Remarks
The HV_MESSAGE_FLAGS union is used in the HV_MESSAGE_HEADER structure.
