Wait... readv(2) defines: ssize_t readv(int fd, const struct iovec *iov, int iovcnt);
It doesn't really matter what the manpage says. What does the AOSP
libc header say?
But the syscall is defined as:
SYSCALL_DEFINE3(readv, unsigned long, fd, const struct iovec __user *, vec,
unsigned long, vlen)
{
return do_readv(fd, vec, vlen, 0);
}
