dwNeededSize The size, in bytes, for this data structure that is needed to hold all the returned information. dwUsedSize The size, in bytes, of the portion of this data structure that contains useful information. dwStringFormat The format of the string. This member uses one of the STRINGFORMAT_Constants. dwStringSize dwStringOffset The size, in bytes, of the variably sized device field that contains the string information and the offset, in bytes, from the beginning of this data structure. If a string cannot be returned in a variable structure, the dwStringSize and dwStringOffset members get set in one of the following ways: • dwStringSize and dwStringOffset members both get set to zero. • dwStringOffset gets set to nonzero and dwStringSize gets set to zero. • dwStringOffset gets set to nonzero, dwStringSize gets set to 1, and the byte at the given offset gets set to zero. ] Wave Functions The AVAudio32.dll implements the wave interfaces to the Cisco wave drivers. The system supports all APIs for input and output waveform devices. Cisco TSP 8.0 includes Cisco Media Driver, a new and innovative way for TAPI-based applications, to provide media interaction. Cisco TSP 8.0(1) includes support for Cisco Media Driver and Cisco Wave Driver. Only one driver is active at any given time. For more information, see Cisco TSP Media Driver, on page 421.
