Yes, with goto many things can be done a lot shorter and also easier to understand.

I've heard many (usually wrong) arguments in favour of gotos, but "easier to understand" is a bold one.

While it's certainly possible to get yourself in so many knots that it's the only way out, I count on one hand the number of times I've used it in the last 35 years, and still have plenty of fingers left.

He's pretty much right. We are talking C here after all. You don't have a lot (or really any) advanced flow control constructs and when you have some function that allocates various resources but can also fail at any given step the cleanest, most efficient and most easy to read option is actually goto. The alternatives would pretty much be either duplicating a lot of code or pointless if statements. Duplication might be an option if it's just 2 or maybe 3 resources that need to be cleaned up but beyond that anything but goto is basically madness and probably not justified by anything but the goto is evil mantra.

For example a part of a minimal http client I wrote some time ago:

if (/* connecting failed */) {
    write_const_stderr("Connecting failed");
    goto err;
}
if (write(sock, /* http request */) < /* request length */) {
    write_const_stderr("Writing failed");
    goto err;
}
if ((read_len = read(sock, buf, 1024)) < strlen(/* mimimal http response */)) {
    write_const_stderr("Reading failed");
    goto err;
}
while (i < read_len && memcmp(&buf[i], "\r\n\r\n", 4) && memcmp(&buf[i], "\n\n", 2)) // not the most efficient, boyer moore would be better
    ++i;
if (buf[i] == '\r')
    i += 4;
else if (buf[i] == '\n')
    i += 2;
else {
    write_const_stderr("Parse error");
    goto err;
}
// process response...
err:
    close(sock);
    // other cleanup, maybe retrying...

That's such a case where something

, for example connecting could fail, reading could fail, the response could not contain a http body, ...

@totally_not_banned said: Duplication might be an option if it's just 2 or maybe 3 resources that need to be cleaned up

But when you add some other resource, you have to add it everywhere, likely some place is forgot and somehow you then inexplicably run out of file descriptors or memory...

I was mostly thinking of something like

    if( !( a = allocate_some_resource1() ) ) {
        return 0;
    }
    if( !( b = allocate_some_resource2() ) ) {
        goto err1;
    }
    if( !( c = allocate_some_resource3() ) ) {
        goto err2;
    }
    // do something ...
    return 1;

err2:
    release_some_resource2( b );
err1:
    release_some_resource1( a );
    return 0;

but in general it's pretty much the same idea as your example, just with more resources added to take care of during failure. At just 3 resources (and a somewhat simple/seldom called cleanup logic) it wouldn't be to bad to just duplicate it and directly return from the if blocks (it's not like a couple bytes of extra code will make much of a difference in 99% of all cases) but beyond that it quickly becomes quite imperative to just centralize the cleanup logic.

Well, it's not like i have much of a choice anymore. Seems someone pushed your only real competition out of business. I'm absolutely puzzled as to who would do such a thing.

Mine is about the thickness of a NVMe, the constant spelling of "run" from my gf makes me confused though.

Don't worry they got some dirt on me too and while i certainly can't be sure, i don't think it was you putting the guy out of business
