win32utils devel - May 2006 - Converting rb_protect + ruby_stop to pure Ruby

Hi,

Within process.c, in the fork method, there''s this bit of code:

if(rb_block_given_p()){
    int status;
    rb_protect(rb_yield, Qundef, &status);
    ruby_stop(status);
}


I translated that as this:

if block_given?
    status = 0
    begin
       yield
    rescue Exception
       status = -1 # Any non-zero result is failure
    end
    exit(status)
end

Is there a way to get the actual status? The $? global isn''t set at
this
point so that doesn''t seem to be an option.  Or is this a reasonable 
default?

This isn''t crucial but I thought I''d ask.

Thanks,

Dan

Here is rb_protect for ruby

def rb_protect
  begin
    yield
  ensure
    return
  end
end

rb_protect { return }
puts ''return stopped''

rb_protect { exit(1) }
puts ''exit stopped''

rb_protect { raise "STOP ME!" }
puts ''raise stopped''

rb_protect { throw(:jump) }
puts ''throw stopped''
