Subject: [PATCH 07/12] vcs-svn: allow input errors to be detected promptly
Date: Sun, 6 Mar 2011 17:10:54 -0600 [thread overview]
Message-ID: <20110306231054.GI24327@elie> (raw)
In-Reply-To: <20110306225419.GA24327@elie>
Date: Sun, 10 Oct 2010 21:51:21 -0500
The line_buffer library silently flags input errors until
buffer_deinit time; unfortunately, by that point usually errno is
invalid. Expose the error flag so callers can check for and
report errors early for easy debugging.
some_error_prone_operation(...);
if (buffer_ferror(buf))
return error("input error: %s", strerror(errno));
