Type Function Library (globals) Return value String Revision 2017.3060 Keywords error, exception, error handling, error message See also pcall()
Terminates the last protected function called (see: pcall()) and returns the first argument as the error message.
Usually, error() adds some information about the error position at the beginning of the message.
error( message [, level] )
String. The message to be returned with the error.
Number. Specifies how to get the error position. With Level 1 (the default), the error position is where the error function was called. Level 2 points the error to where the function that called error was called; and so on. Passing a level 0 avoids the addition of error position information to the message.
