From 5094102e13640d7559a02fd7c77b44dc9254cbbb Mon Sep 17 00:00:00 2001 From: Daniel Barkalow Date: Wed, 2 May 2007 22:49:41 -0400 Subject: Make xstrndup common This also improves the implementation to match how strndup is specified (by GNU): if the length given is longer than the string, only the string's length is allocated and copied, but the string need not be null-terminated if it is at least as long as the given length.
