Function Documentation

PaError PaAlsa_Initialize	(	PaUtilHostApiRepresentation **	hostApi,
		PaHostApiIndex	index
	)

PaError PaAsiHpi_Initialize	(	PaUtilHostApiRepresentation **	hostApi,
		PaHostApiIndex	index
	)

PaError PaJack_Initialize	(	PaUtilHostApiRepresentation **	hostApi,
		PaHostApiIndex	index
	)

PaError PaOSS_Initialize	(	PaUtilHostApiRepresentation **	hostApi,
		PaHostApiIndex	hostApiIndex
	)

Initialize the OSS API implementation.

This function will initialize host API datastructures and query host devices for information.

Aspect DeviceCapabilities: Enumeration of host API devices is initiated from here

Aspect FreeResources: If an error is encountered under way we have to free each resource allocated in this function, this happens with the usual "error" label.

PaError PaSGI_Initialize	(	PaUtilHostApiRepresentation **	hostApi,
		PaHostApiIndex	index
	)

Variable Documentation

int paDefaultHostApiIndex = 0

The index of the default host API in the paHostApiInitializers array.

There is a platform specific file which defines paDefaultHostApiIndex for that platform, see pa_win/pa_win_hostapis.c for example.

PaUtilHostApiInitializer* paHostApiInitializers[]

Initial value:

    {











                    







        0   
    }

paHostApiInitializers is a NULL-terminated array of host API initialization functions. These functions are called by pa_front to initialize the host APIs when the client calls Pa_Initialize().

There is a platform specific file which defines paHostApiInitializers for that platform, pa_win/pa_win_hostapis.c contains the Win32 definitions for example.
