| // For seamonster we register an exit handler to do the following: |
| // |
| // Do nothing if the function was already called |
| // |
| // Do nothing if SM was not initialized |
| // |
| // If this is not the reader thread |
| // Send the reader thread a SHUTDOWN message |
| // Wait for reader thread to react |
| // |
| // SM_cancel ID used internally by executor code |
| // |
| // SM_finalize |
| // |
| // An older version of this file described a requirement which no |
| // longer exists: that no thread should call SM_finalize if another |
| // thread is inside a seamonster API call. This requirement has gone |
| // away. |
| // |
| // In addition, the old code relied on state variables in the main |
| // thread and reader thread to track SM initialization calls being |
| // made (an older API had several initialization calls such as |
| // SM_reader_connect). Now the goal is much simpler: if a process has |
| // called SM_init successfully, try to call SM_finalize before the |
| // process exits. |
