Sure, it's my mistake, it should be file.tmp not file.swp:
fd = open("file");
read(fd, buffer, size);
close(fd);
copy("file", "file~");
[...here user edits file...]
fd = open("file.tmp", O_WRONLY|O_CREAT|O_TRUNC);
write(fd, "new content of file");
close(fd);
chmod("file.tmp", mode);
chown("file.tmp", owner, group);
[...if need be, setting other parameters like ACLs...]
rename("file.tmp", "file");
