Partial regex

Question

I have a regex that I'm testing a character input stream. I wonder if there is a way to match the regex to the input and determine if this is a partial match that consumes the entire input buffer? That is, the end of the input buffer will be reached before regexp completes. I would like the implementation to decide whether to wait for more character input or to abort the operation.

In other words, I need to determine which one is true:

• The end of the input buffer was reached before regex matching

  eg. "foo" =~ /^foobar/

• Regular expression is exactly the same as

  eg. "foobar" =~ /^foobar/

• Regular expression does not match

  eg. "fuubar" =~ /^foobar

Entrance is not packetized.
