From 447dc1efebac1484d5903ba34655289e7725df6d Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 3 Oct 2024 14:54:43 -0400 Subject: [PATCH] xdrgen: XDR width for pointer types The XDR width of a pointer type is the sum of the widths of each of the struct's fields, except for the last field. The width of the implicit boolean "value follows" field is added as well.
