Hi, I accidentally came across this: The abort(3) man page says "[...] all open streams are closed and flushed" With glibc-2.27, to be released pretty soon now, file descriptors will no longer be flushed. See near the bottom of https://sourceware.org/glibc/wiki/Release/2.27 . cheers, egmont -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
