Add a timestamp on the hot-path.
As this is on the hot-path minimal processing is done. The location to be written to is loaded using a technique that minimises cache usage: this might be slightly slower, but attempts to avoid overwriting the entire contents of each cache in the hierarchy. Note that this function is thread-safe & re-entrant safe.
Implements jmmcg::LIBJMMCG_VER_NAMESPACE::latency_timestamps_itf.

◆ to_csv()
|
noexcept |
Write the timestamps, if any, to the output-stream.
- Parameters
-
os The output stream to which the timestamps, in CSV format, should be written.

◆ write_to_csv_file()
|
noexcept |
Wrtie the timestamps, if any, to a CSV file.
- Parameters
-
os Write log output to this output stream. root Write the timestamps, in CSV format, to a file with the filename root as specified. Unique identifying text will be appended and ".csv" shall be the extension.

◆ write_to_named_csv_file()
|
noexcept |
Wrtie the timestamps, if any, to the named CSV file.
- Parameters
-
os Write log output to this output stream. base_filename Write the timestamps, in CSV format, to a file with the base of the filename as specified, the extension ".csv" will be appended.
