msbdnOutputGetValueCount

[This is preliminary documentation and subject to change.]

The msbdnOutputGetValueCount function retrieves the upper bound on the number of indexes of configuration values that the virtual interface DLL supports.

HRESULT msbdnOutputGetValueCount(
  IN MSBDN_OUTPUT_SUBSYSTEM *Subsystem,
  OUT DWORD *ValueCount    
);
 

Parameters

Subsystem

Address of an MSBDN_OUTPUT_SUBSYSTEM structure that contains details about the virtual interface implementation.

ValueCount

Address of a value that specifies the upper bound on the number of indexes of configuration values that the virtual interface DLL supports. Usually, this value is a constant.

Return Values

Should always return zero for a successful status.

Remarks

The MMR calls msbdnOutputGetValueCount to obtain the number of dynamic configuration parameters the output system might support. For example, if an output system supports a serial-port value, a bit-rate value, and a framing-mode value, msbdnOutputGetValueCount should store the number three in the memory to which the ValueCount parameter points.
