Subject: What is the meaning of rb_thread_interrupted() ?

Hi, I'm coding a Ruby C extension and would like to know the meaning
of  rb_thread_interrupted() function defined in thread.c, whose
content is:


/* This function can be called in blocking region. */
int
rb_thread_interrupted(VALUE thval)
{
    rb_thread_t *th;
    GetThreadPtr(thval, th);
    return RUBY_VM_INTERRUPTED(th);
}


And RUBY_VM_INTERRUPTED(th) is defined as:


#define RUBY_VM_INTERRUPTED(th) ((th)->interrupt_flag & 0x02)


So, when does rb_thread_interrupted() return 1 or 0?

Thanks a lot.
