XCode 2.2: warning: 'i' may be used uninitialized in this function.

I'm getting a warning from XCode 2.2 that 'i' could be used un-initialised in the function below.

bar() returns zero if it fails or returns 1 on success and sets 'i' to a value.

Is this really an issue that XCode should treat as a warning? or has XCode analysed bar() and determined that I have an issue in bar() where I might return '1' without setting 'i'?

/Users/rob/Work/atMacXt/common.c:791: warning: 'i' may be used uninitialized in this function

void foo ()

{

int i;

if (!bar (&i))

return;

func (i);

}

Regards, Rob.
