Function Reference

The Function Reference Page Format

• The function name
• The purpose of the function
• The function syntax

All valid input argument and output argument combinations are shown. In some cases, an ellipsis (. . .) is used for the input arguments. This means that all preceding input argument combinations are valid for the specified output argument(s).

• A description of each argument
• A description of the function
• An example of usage

Some function examples are constructed explicitly for sound cards or National Instruments boards. However, for most of these device-specific examples, the functionality illustrated applies to all supported devices. If device-specific properties or values are used, or if the illustrated behavior depends on the device, then this is explained in the example.
