RemTail

remove the tail node from a list

Remove the last node from a list, and return a pointer to it. If the list is empty, return zero. Assembly programmers may prefer to use the REMTAIL macro from "exec/lists.i". The REMTAIL() macro from <exec/list_macros.h> is available for 'C' programmers.

This function does not arbitrate for access to the list. The calling Task must be the owner of the involved list.
