BASH: how can I save the exit code in PS1 in order to use it later in PS1?

I am attempting to customize my PS1, in the following way (I have removed the colours):

PS1='u@h:w$(git_branch)$(useExitCode)$ '

where

git_branch()
 sed -e '/^[^*]/d' -e 's/* (.*)/(1)/'

As for exit status, I would like to pick it up before the git_branch function is executed, and use it in useExitCode . How can I do that? The latter function could look like this:

useExitCode()

 local exitCode=$1

 if [[ $exitCode == 0 ]]; then
 echo ':)'
 else
 echo ':('
 fi

The question is, how can I store the exitcode in PS1 and use it later ?

Something like the following does not work, but gives an idea of the geenral direction:

PS1='exitCode=$?u@h:w$(git_branch)$(useExitCode $exitCode)$ '

The above echo's the "exitCode=0" (or =1) part but it is not stored, so it is empty at its invocation "$exitCode" later.

Thank you in advance for your help
