Type Function Library (globals) Return value String Revision Current Public Release (2017.3068) 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.
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.
