Required inputs: IR, StaticSemanticAnalysis

This check detects resources which require a certain operation (call to a function), but that call was missing.

Possible Messages

Type: dict[str, dict[str, dict[str, bool | str]]]

Default:

{
   'Thread': {
      'Detaching a running thread.': {
         'Required_Functions': 'std::thread::detach'
      },
      'Joining a running thread.': {
         'Required_Functions': 'std::thread::join'
      }
   }
}

Dict which lists required operations per resource. The mapping gives each case a description which maps to a dict for key "Required_Functions".

 

resources

resources : set[str] = {'Thread'}

Set of resources to be checked (selection of rules in the Resources group).
