ESMF_VMGetCurrentID Subroutine

  subroutine ESMF_VMGetCurrentID(vmId, rc)
!
! !ARGUMENTS:
    type(ESMF_VMId), intent(out)           :: vmId
    integer,         intent(out), optional :: rc
!
! !DESCRIPTION:
!   Get the {\tt ESMF\_VMId} of the current execution context.
!
!   The arguments are:
!   \begin{description}
!   \item[vmId] 
!     Upon return this holds the {\tt ESMF\_VMId} of the current context.
!   \item[{[rc]}] 
!     Return code; equals {\tt ESMF\_SUCCESS} if there are no errors.
!   \end{description}
