Breaking out of functions

[chris1985]

I have a program which I am trying to use to detect if there is a temporary disconnect from the internet. If there is then once the connection is detected a function called recovery() is called to set up and initalise things that will have broken. Throughout the recovery function I need to constantly be checking that the connection is still working and has not broken again half way through the recovery process. So what I proposed was something like the code below.

The idea is to start the recovery function from the beginning if at any time a disconnect occurs a second time. However as I understand it, if recovery calls recovery from itself then once the second recovery has finished, then the first recovery will try to continue from where it left off. Therefore I need something in recovery that breaks out of itself and goes back to whatever function called it originally. I considered using break however I believe this only breaks out of the IF statement and not the whole function. Can anyone tell me of a function a bit like Break but that exits the whole function (but not the whole program).

Thankyou in advance for your help,
Chris

void recovery(void){

//Some other code goes here

	if(connected == NULL)
	{
		recovery();
		break;
	}



//Insert other code goes in here


	if(connected == NULL)
	{
		recovery();
		break;
	}

//more code here


//if statement again here etc....

What you want is return. Just like break, but it exits the current function, returning any optional value you want to. Examples:

void foo( void )
{
    ...
    return; /* function returns 'void', that is to say, nothing... */
}

...

int bar( void )
{
    int x;
    ...
    return x; /* function returns an int, here we decide to return whatever 'x' has in it... */
}

As quazah said, you need to return a value to break out of a function. If you want the function to restart, just make it return -1 (for error). In that case you can call it with the line:
while(recovery());
