Subject: Test the __fpending function.
X-Git-Tag: v5.3.0~208
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff13a286c7769664614d835c09653c83fcb1cb6c;p=thirdparty%2Fcoreutils.git

Test the __fpending function.
This ensures that if there is an error in the definition of the
PENDING_OUTPUT_N_BYTES expression, we'll find about it right away;
that value is used only in the rare event that close_stdout's
fclose fails with EBADF.
