Yes, but the precedence of ==, <, and > is even higher.
However, I've found a problem with the previous patch: The first chunk should
read:
- if((len = sendfile(session.d->outf->fd, retr_fd, offset, count)) == -1) {
+ len = sendfile(session.d->outf->fd, retr_fd, offset, count);
+ if (len == -1 || len > 0 && len < count) {
+ if (len != -1)
+ errno = EINTR;
i.e. we should not overwrite errno, when it is valid.

PS.: You can find the C operators precedence for example at
