 other options specific to the report

DETAILS¶

Any number of coverage databases may be specified on the command line. These databases will be merged and the reports will be based on the merged information. If no databases are specified the default database (cover_db) will be used.

The -write option will write out the merged database. If no name is given for the new database, the first database read in will be overwritten. When this option is used no reports are generated by default.

Specify -select and -ignore options to report on specific files. Specify -coverage options to report on specific criteria. By default all available information on all criteria in all files will be reported.

The -test option will delete the databases and run make test to generate new coverage data before reporting on it. The -gcov option will try to run gcov on any XS code. This requires that you are using gcc of course. If you are this option will be turned on by default.

EXIT STATUS¶

The following exit values are returned:

0 All operations were completed successfully.

>0 An error occurred.
