Seed of Random number generation

Dear all, is it possible to extract the seed that was used for some random
number generation? For example suppose I draw a random sample of size 1000
from a normal population :

rnorm(1000)

Now I want to know what seed R used for that sample generation. Any way out?

Thanks and regards,

I believe R creates a random seed after a random number generation function
such as rnorm is called. The seed is stored in the vector .Random.seed  .
See ?RNG for more info on how to load, save and tweak the random seed.

... which means that you cannot get the seed that has been used in a 
step before, but you can save (or set) the seed before calling 
rnorn(1000), of course.
