************** script_error() ************** Purpose ======= script_error() Returns the error state of functions that support it. C-Developers note that this is similar to ``errno`` under Linux. The error state corresponds to the function immediately called before. The next function call overrides it. Right now, the value 0 means that the previous functions succeeded, any other value that it failed. In the future, we may have more fine-grain error codes. Function descriptions mention if a function supports error state information. If not, the function call will always set ``script_error()`` to 0. Example ======= The following example shows that script_error() only needs to be called and does not need any parameters. .. code-block:: none script_error()
