Refresh main function?

[pj1115]

Hey

Quick question:
If I was in the middle of the main function, would there be a way to start from the beginning again, like restart it? (ie, could I use main(); or is there another way)?

It's better to use a while loop, but you could use labels
e.g.

Code: Select all

void main(void) {
start:
printf("blah/n");
// do stuff
if (...) goto start;
}

Thanks a bunch, jas0nuk!

Expect a release from me in a few hours! :)

Oh, and I have another question.

I'm not using callbacks (so there's no "Do you want to exit the game?" screen), and in my program I'm using:

Code: Select all

if(pad.Buttons & PSP_CTRL_HOME) {
                pspDebugScreenClear();
                printf("\n\n\n\n\n\n\n\n\n\n Bye, Bye! \n\n"
                "- This has been a pj1115 production!");


		sceKernelDelayThread(10*1000*1000);

		sceKernelExitGame();
}

But when I press [Home], it doesn't do anything. Is there something wrong with my code?

Your program needs to run in kernel mode when you want to catch the home button. I had the same problem recently.

Thanks, worked like a charm!

I'm releasing it now, it's called 'Outa-Space PSP'.

Here's the download, and I've submitted it to QJ.

Using lables and goto - bad style. I prefer:

Code: Select all

for(...;...;...)
{
    ...
    if(...) continue;
    ...
}

Using labels and gotos is only considered bad style if you buy into the whole "structured" programming style. If you aren't trying to be 100% structured, there's absolutely nothing bad about using labels and gotos in any manner at all.

I think they push structured programming style too much these days. It's one of the main contributors to code bloat.

You'll find a lot of debate about goto/labels...
In certain cases, and if you're a good programmer, you can make clean and efficient use of goto and labels; the Linux kernel for example uses them frequently for clean error handling.
But for most new programmers, it's recommended that you just steer clear of them completely, as they can quickly lead to bad habits and keep you from learning other useful code structures like do/while, switch/case, etc.

not to mention you goto somewhere; and you miss closing
a file pointerf or even opening one :P ....this is most common
problem

These "problems" and "bad habits" people like to claim are more prevalent in non-structured programs are just as common in structured programs in my experience. Not closing files or freeing memory is due to a poorly constructed program, not the style of construction.
