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 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.
