• callback {Function} The callback function
    • Returns: {Function} The bound function

    The returned function will be a wrapper around the supplied callback function. When the returned function is called, any errors that are thrown will be routed to the domain’s 'error' event.

    1. const d = domain.create();
    3. function readSomeFile(filename, cb) {
    4.   fs.readFile(filename, 'utf8', d.bind((er, data) => {
    5.     // If this throws, it will also be passed to the domain.
    6.     return cb(er, data ? JSON.parse(data) : null);
    7.   }));
    8. }
    10. d.on('error', (er) => {
    11.   // An error occurred somewhere. If we throw it now, it will crash the program
    12.   // with the normal line number and stack message.
    13. });
