From: Sebastian Huber <sh@sourceware.org> To: newlib-cvs@sourceware.org Subject: [newlib-cygwin] Add _REENT_CVTLEN(ptr) Date: Wed, 13 Jul 2022 08:19:53 +0000 (GMT) [thread overview] Message-ID: <20220713081953.51BF33857BBC@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=315c420e1becee5dc5dbe6fad5ffc1a447ea2e48 commit 315c420e1becee5dc5dbe6fad5ffc1a447ea2e48 Author: Matt Joyce <matthew.joyce@embedded-brains.de> Date: Thu Feb 3 11:19:14 2022 +0100 Add _REENT_CVTLEN(ptr) Add a _REENT_CVTLEN() macro to encapsulate access to the _cvtlen member of struct reent. This will help to replace the struct member with a thread-local storage object in a follow-up patch.
