SET_UNIT_INFO structure (61883.h)
This structure is used to set unit information.
The Av61883_SetUnitInfo request sets the parameters that the IEC-61883 protocol driver should use when capturing and transmitting isochronous packets.
Syntax
typedef struct _SET_UNIT_INFO {
IN ULONG nLevel;
IN OUT PVOID Information;
} SET_UNIT_INFO, *PSET_UNIT_INFO;
Members
nLevel
On input, the level of information to retrieve. Can be one of the following:
SET_UNIT_INFO_DIAG_LEVEL
SET_UNIT_INFO_ISOCH_PARAMS
SET_CMP_ADDRESS_RANGE_TYPE
Information
On input, if nLevel is SET_UNIT_INFO_DIAG_LEVEL, this member is a pointer to a caller-allocated and initialized UNIT_DIAG_LEVEL structure.
If nLevel is SET_UNIT_INFO_ISOCH_PARAMS, this member is a pointer to a caller-allocated UNIT_ISOCH_PARAMS structure.
If nLevel is SET_CMP_ADDRESS_RANGE_TYPE, this member is a pointer to a caller-allocated SET_CMP_ADDRESS_TYPE structure.
Remarks
If successful, the IEC-61883 protocol driver sets Irp->IoStatus.Status to STATUS_SUCCESS.
If an incorrect parameter is passed in, the protocol driver sets Irp->IoStatus.Status to STATUS_INVALID_PARAMETER.
