Detailed Description

A structure containing information about a particular host API.

Field Documentation

PaDeviceIndex PaHostApiInfo::defaultInputDevice

The default input device for this host API. The value will be a device index ranging from 0 to (Pa_GetDeviceCount()-1), or paNoDevice if no default input device is available.

Referenced by main(), PaAsiHpi_Initialize(), PaAudioIO_Initialize(), PaPulseAudio_Initialize(), and PaPulseAudio_StartStreamCb().

PaDeviceIndex PaHostApiInfo::defaultOutputDevice

The default output device for this host API. The value will be a device index ranging from 0 to (Pa_GetDeviceCount()-1), or paNoDevice if no default output device is available.

int PaHostApiInfo::deviceCount

The number of devices belonging to this host API. This field may be

used in conjunction with Pa_HostApiDeviceIndexToDeviceIndex() to enumerate all devices for this host API.
