That's a good observation. What cloudlibc does is that it leaves IOV_MAX undefined, as there is no compile-time maximum. It is therefore perfectly legal to use UIO_MAXIOV in this specific piece of code, as long as it is consistent with sysconf(_SC_IOV_MAX). If my interpretation of POSIX is correct, this should be allowed. Many of the definitions in <limits.h> may be omitted if the actual limit is unspecified.
