[edit] Description
JS_SetErrorReporter enables you to define and use your own error reporting mechanism in your applications. The reporter you define is automatically passed a JSErrorReport structure when an error occurs and has been parsed by JS_ReportError.
Typically, the error reporting mechanism you define should log the error where appropriate (such as to a log file), and display an error to the user of your application. The error you log and display can make use of the information passed about the error condition in the JSErrorReport structure.
