Function Documentation

PaError PaAsio_GetAvailableLatencyValues ( PaDeviceIndex  device,
long *  minLatency,
long *  maxLatency,
long *  preferredLatency,
long *  granularity 
)

Retrieve legal latency settings for the specificed device, in samples.

Parameters:
device The global index of the device about which the query is being made.
minLatency A pointer to the location which will recieve the minimum latency value.
maxLatency A pointer to the location which will recieve the maximum latency value.
preferredLatency A pointer to the location which will recieve the preferred latency value.
granularity A pointer to the location which will recieve the granularity. This value determines which values between minLatency and maxLatency are available. ie the step size, if granularity is -1 then available latency settings are powers of two.

Todo:
This function should have a better name, any suggestions?

PaError PaAsio_ShowControlPanel ( PaDeviceIndex  device,
void *  systemSpecific 
)

Display the ASIO control panel for the specified device.

Parameters:
device The global index of the device whose control panel is to be displayed.
systemSpecific On Windows, the calling application's main window handle, on Macintosh this value should be zero.

PaError PaAsio_GetInputChannelName ( PaDeviceIndex  device,
int  channelIndex,
const char **  channelName 
)

Retrieve a pointer to a string containing the name of the specified input channel. The string is valid until Pa_Terminate is called.

The string will be no longer than 32 characters including the null terminator.

PaError PaAsio_GetOutputChannelName ( PaDeviceIndex  device,
int  channelIndex,
const char **  channelName 
)

Retrieve a pointer to a string containing the name of the specified input channel. The string is valid until Pa_Terminate is called.

The string will be no longer than 32 characters including the null terminator.
