Using Goto function across different functions

Question

How can I use goto function across different functions .For ex ,

    main()
    {
      ....
      REACH:
      ......
    }

    void function()
    {
             


        

Answer 1

You can't in Standard C; labels are local to a single function.

The nearest standard equivalent is the setjmp() and longjmp() pair of functions.

GCC has extensions to support labels more generally.
