smuX.buffer.getstats()

This function returns a specified reading buffer's statistics.
Type TSP-Link accessible
Function Yes
Usage
statistics = smuX.buffer.getstats(bufferVar)

Details
This function returns a table with statistical data about the data that is placed in the buffer.
The SMU automatically updates reading buffer statistics as data is added to the reading buffer. When the
reading buffer is configured to wrap around and overwrite older data with new data, the buffer statistics include
the data that was overwritten.
The table returned from this function is a snapshot. Although the SMU continues to update the statistics, the
table returned is not updated. To get fresh statistics, call this function again.
The statistics parameter has the attributes described in the following table.
