Exit codes - GridLAB-D exit codes
The GridLAB-D core solver and most GridLAB-D modules use the following exit code:
- -1 exec failed
- 0 success
- 1 bad command line
- 2 environment startup failed
- 3 test failed
- 4 user rejected terms of use
- 5 simulation did not complete as desired
- 6 initialization failed
- 7 process control error
- 8 server killed
- 9 I/O error
- 127 shell failure
- 128-254 signal received (low order bits are signal number)
- 255 exception caught
Caveat
Some libraries used by GridLAB-D module do not following the GridLAB-D exit code standard.
Some systems cannot distinguish between -1 and 255.
