    4646The inputDriverInfo and outputDriverInfo fields to Pa_OpenStream() will be moved to the PaStreamParameters structure described in <A HREF="016-UseStructsForOpenStreamParameters.html">016 - Use Structs for Pa_OpenStream() Parameters</A>. The equivalent field in this structure will be a void* field named hostApiSpecificStreamInfo.

    50 A special constant paNullStreamInfo will be defined, which can be used in the inputStreamInfo 
    51 and outputStreamInfo parameters.

     173Originally A special constant paNullStreamInfo was to be defined, which coud be used in the inputStreamInfo and outputStreamInfo parameters. However since the introduction of the PaStreamParameters structure there is no longer any benefit to having a constant which  
     174indicates the role of the value.

    182184When PaHostApiSpecificStreamInfo was still declared, we intended to change the type of the 
    183185streamInfo parameters from void* to PaHostApiSpecificStreamInfo*. Some objections were raised
