Constructor & Destructor Documentation

PeekSigInfo()

cosmos::ptrace::PeekSigInfo::PeekSigInfo ( )

inline

Creates an object with default settings.

The Flag::PEEK_SHARED setting is applied, since this is the typical request that will be needed. All other members are set to zero.

Definition at line 255 of file ptrace.hxx.

                      {
                clear();
                setFlags(Flags{Flag::PEEK_SHARED});
        }
