- @brief Implements public PortAudio API, checks some errors, forwards to
- host API implementations.
+ @brief Implements PortAudio API functions defined in portaudio.h, checks 
+ some errors, delegates platform-specific behavior to host API implementations.
  
- Implements the functions defined in the PortAudio API, checks for
- some parameter and state inconsistencies and forwards API requests to
- specific Host API implementations (via the interface declared in
- pa_hostapi.h), and Streams (via the interface declared in pa_stream.h).
+ Implements the functions defined in the PortAudio API (portaudio.h), 
+ validates some parameters and checks for state inconsistencies before 
+ forwarding API requests to specific Host API implementations (via the 
+ interface declared in pa_hostapi.h), and Streams (via the interface 
+ declared in pa_stream.h).
 
- This file handles initialization and termination of Host API
- implementations via initializers stored in the paHostApiInitializers
- global variable.
+ This file manages initialization and termination of Host API
+ implementations via initializer functions stored in the paHostApiInitializers
+ global array (usually defined in an os-specific pa_[os]_hostapis.c file).
+
+ This file maintains a list of all open streams and closes them at Pa_Terminate().
 
  Some utility functions declared in pa_util.h are implemented in this file.
