Documentation

Class representing a task on the PVM.

This class represents a task, running (or preveously running) on the PVM. Internally it just stores a pointer to a data structure, so it is save and fast to use it as a value parameter and as a function result as well. Requests to the PVM, like Name() are cached, so you don't need to cache yourself.

There is an ostream& operator<< (ostream &Stream, Task What) defined as well. It outputs the task id as used by the PVM prepended by a "t".

o Task(unsigned int What)
constructs a Task for the host with the task id What as used by PVM.

o operator unsigned int () const
returns the host id as used by PVM.

obool HasParent() const
returns, whether the task has a parent.

oTask Parent() const
returns the parent of the task. It is an error to call this function, if no parent exists. Use HasParent() to check.

o::Pvm::Host Host() const
returns the host, the task is running on.

ostd::string Name() const
returns the name of the task. The name is only available for programs started by PVM++ via a Spawn() call or started by PVM using the pvm_spawn() call. This is a limitation inherited from PVM.

obool Running() const
returns, whether the task is running.

ovoid Kill() const
kills the tasks.
