PaError PaAsio_GetAvailableBufferSizes | ( | PaDeviceIndex | device, | |
long * | minBufferSizeFrames, | |||
long * | maxBufferSizeFrames, | |||
long * | preferredBufferSizeFrames, | |||
long * | granularity | |||
) |
Retrieve legal native buffer sizes for the specificed device, in sample frames.
device | The global index of the device about which the query is being made. | |
minBufferSizeFrames | A pointer to the location which will receive the minimum buffer size value. | |
maxBufferSizeFrames | A pointer to the location which will receive the maximum buffer size value. | |
preferredBufferSizeFrames | A pointer to the location which will receive the preferred buffer size value. | |
granularity | A pointer to the location which will receive the "granularity". This value determines the step size used to compute the legal values between minBufferSizeFrames and maxBufferSizeFrames. If granularity is -1 then available buffer size values 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.
The string will be no longer than 32 characters including the null terminator.
Set the sample rate of an open paASIO stream.
stream | The stream to operate on. | |
sampleRate | The new sample rate. |
Returns paIncompatibleStreamHostApi if stream is not a paASIO stream.
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. |
