Member Function Documentation
bool NullProcessInfo::readProcessInfo | ( | int | pid, | |
bool | readEnvironment | |||
) | [protected, virtual] |
This is called on construction to read the process state Subclasses should reimplement this function to provide platform-specific process state reading functionality.
When called, readProcessInfo() should attempt to read all of the necessary state information. If the attempt is successful, it should set the process id using setPid(), and update the other relevant information using setParentPid(), setName(), setArguments() etc.
Calls to isValid() will return true only if the process id has been set using setPid()
- Parameters:
-
pid The process id of the process to read readEnvironment Specifies whether the environment bindings for the process should be read
