elisp: set-register

[Dan Elliott]

Hello,

I am having difficulty understanding the set-register function.  When I try:
(set-register ?p (current-window-configuration))

in a function run by my .emacs file, it does not appear to work, nor does it
appear to cause an error.

I want to set the current window config to 'p'.

Am I going about this the wrong way?

Thank you,
