These commands are used to perform various utility tasks with waveform traces usually referenced in Trace4.0 schema database tables. For now the only functions are in support of the magnitude estimation perl computational scripts used by orbevproc(1), however they can be used in other perl scripts and this extension library is meant to expand as new functions become necessary. Coding these functions in C instead of in native perl greatly increases the performance. The trace perl commands are as follows:
