Member Function Documentation
◆ cancel()
|
virtual |
Cancel the thread.
Equivalent to SIGKILL.
- Returns
- 0 if normal, -1 if errno set, errno code otherwise.
Reimplemented from OpenThreads::Thread.
◆ run()
|
virtual |
Thread's run method.
Must be implemented by derived classes. This is where the action happens.
Implements OpenThreads::Thread.
The documentation for this class was generated from the following file:
