PaError PaAsio_GetAvailableLatencyValues | ( | PaDeviceIndex | device, | |
long * | minLatency, | |||
long * | maxLatency, | |||
long * | preferredLatency, | |||
long * | granularity | |||
) |
Retrieve legal latency settings for the specificed device, in samples.
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. |

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.

PaError PaAsio_ShowControlPanel | ( | PaDeviceIndex | device, | |
void * | systemSpecific | |||
) |
Display the ASIO control panel for the specified device.
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. |
