In your .h file...

Boo.foo = foo;
}
public static void randomMethod() {
foo.doStuff();
}
}

How to automatically generate a stacktrace when my program crashes
...e_symbols_fd(array, size, STDERR_FILENO);
exit(1);
}
void baz() {
int *foo = (int*)-1; // make a bad pointer
printf("%d\n", *foo); // causes segfault
}

if foo; then ... # "if the command foo succeeds, return true"
So:
if [ true ] ; then echo "This text will always appear." ; fi;
if [ false ] ; then echo ...
