If we're going for maximum readability, I'd actually split
+ else if (fileFlags & (O_TEXT | O_BINARY) &&
+ _setmode(fd, fileFlags & (O_TEXT | O_BINARY)) < 0)
into two different if statements as wlel. Ee.g.
else if (fileFlags (O_TEXT | O_BINARY)) {
if (_setmode() < 0) {
failure();
}
}
Haven't tested the patch yet, but it looks ok.
