P4_N_TO_LINK(3)

NAME
p4_n_to_link - N>LINK ( nfa -- lfa )

SYNOPSIS

#include <pfe/header-ext.h>

FCode p4_n_to_link(---);

DESCRIPTION

converts a pointer to the name-field (NFA) to point then to the corresponding link-field (LFA) - this operation is quicker than the inverse L>NAME. This word is a specific implementation detail and should not be used by normal users - instead use always NAME> which is much more portable. Many systems may possibly not even have a >LINK-field in the sense that a @ on this adress will lead to another >NAME. Any operation on the resulting >LINK-adress is even dependent on the current configuration of PFE - only in fig-mode you are asserted to have the classic detail. (and fig-mode did not know about SYNONYMs - see note at LINK>).

      implementation-specific configure-dependent fig-only simulation:
        : N&gt;LINK  C@ + ;
