-/** @file
- @brief Functions to assist in measuring the CPU utilization of a callback
- stream. Used to implement the Pa_GetStreamCpuLoad() function.
-
- @todo Dynamically calculate the coefficients used to smooth the CPU Load
- Measurements over time to provide a uniform characterisation of CPU Load
- independent of rate at which PaUtil_BeginCpuLoadMeasurement /
- PaUtil_EndCpuLoadMeasurement are called.
