If you are collecting coverage data, and are interested in checking coverage for only a portion of a program, use the Purify API functions CoverageStartRecordingData, CoverageStopRecordingData, and CoverageClearData to control data recording.
Note:
§ You can also exclude modules whose coverage data does not interest you by selecting Exclude in the Module Instrumentation dialog box.
