◆ HasConsistentHashMember() [1/2]

Bool_t ROOT::Internal::HasConsistentHashMember ( const char *  cname)

Return true is the Hash/RecursiveRemove setup is consistent, i.e.

when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation. This routines is used for a small subset of the class for which we need the answer before gROOT is properly initialized.

◆ LogicalCPUBandwidthControl()

int ROOT::Internal::LogicalCPUBandwidthControl ( )

Returns the available number of logical cores.

  • Checks if there is CFS bandwidth control in place (linux, via cgroups, assuming standard paths)
  • Otherwise, returns the number of logical cores provided by std::thread::hardware_concurrency()

◆ MinimalErrorHandler()

void ROOT::Internal::MinimalErrorHandler ( Int_t  level,
Bool_t  abort_bool,
const char *  location,
const char *  msg 
)

A very simple error handler that is usually replaced by the TROOT default error handler.

The minimal error handler is not serialized across threads, so that output of multi-threaded programs can get scrambled

Note
abort() is only called if abort_bool is true and level >= gErrorIgnoreLevel
