Implementing Scoped Defer in C

Why "(ab)use" goto ? Use it with pleasure! Solution from Linus Torwalds:

    int somefunc(...) {
        int ret = E_OK;
        FILE *a = NULL;
        FILE *b = NULL;
        FILE *c = NULL;

        if(!(a == fopen("a.txt",...)) {
            ret = E_A_FAILED;
            goto end;
        }

        if(!(b == fopen("b.txt",...)) {
            ret = E_B_FAILED;
            goto end;
        }

        if(!(b == fopen("b.txt",...)) {
            ret = E_C_FAILED;
            goto end;
        }

        /* do your fancy stuff here */

        end:

        if(a)
            fclose(a);
        if(b)
            fclose(b);
        if(c)
           fclose(c);

        return ret;
    }
