Totalsize (4 bytes): An unsigned 32-bit integer. The total size, in bytes, of this packet and any trailing variable-length data.

InitContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified session value that MUST be equal to the InitContext value specified in the original scoping of the line Initialize request.

lpContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified value that MUST be equal to the lpContext value in the original request.

hDevice (4 bytes): An unsigned 32-bit integer. This MUST be ignored on receipt and can be any value.

Msg (4 bytes): An unsigned 32-bit integer. The packet type identifier. MUST be set to LINE_REPLY (0x0000000C).

OpenContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified value that MUST be equal to the OpenContext value specified in the original scoping of the line Open request.

dwRequestId (4 bytes): An unsigned 32-bit integer. The positive, nonzero, client-specified request ID value equal to the dwRequestId value in the original request.

Result (4 bytes): An unsigned 32-bit integer. The request result, for example, 0 for success or a LINEERR_Constants value for an error.

lpParamsContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified value that MUST be equal to the lpParamsContext value in the original line DevSpecific request.

dwSize (4 bytes): An unsigned 32-bit integer. The size, in bytes, of any returned variable-length data that immediately follows this packet.

VarData (variable): Contains opaque data of the size specified by dwSize. The contents of this field MUST be QWORD-aligned, as specified in [MS-DTYP] section 2.2.40.
