// C code, it is natural to return -1 for errors and 0 for success.

// Therefore, the code that interacts directly with the worker uses this
|
|
// convention (note: command functions do get boolean results since the
|
|
// command always succeeds and we do a string/boolean check for the
|
|
// expected results).
