Member Function Documentation

CheckAccessDeleted::size_type zypp::CheckAccessDeleted::check ( bool  verbose_r = false)

Check for running processes which access deleted executables or libraries.

Per default check will try guess and collect executables and libraries only by looking at the files path and name. (e.g named lib* or located in *bin/).

A verbose check will omit this test and collect all processes uning any deleted file.

Returns
the number of processes found.
Exceptions
ExceptionOn error collecting the data (e.g. no lsof installed)
