I'm having real trouble following your logic there. How does the order get reversed? Why does it print 5342 when 78, uio, and 56 are all absent? Do you really mean the 5th line and only the 5th line?

uio.h(3HEAD) Headers uio.h(3HEAD)
NAME
uio.h, uio - definitions for vector I/O operations
SYNOPSIS
#include <sys/uio.h>
DESCRIPTION
The <sys/uio.h> header defines the iovec structure, which includes the following members:
void *iov_base /* base address of a memory region for input or output */
size_t iov_len /* size of the memory pointed to by iov_base */
The <sys/uio.h> header uses the iovec structure for scatter/gather I/O.
The ssize_t and size_t types are defined as described in <sys/types.h>.
USAGE
The symbol {IOV_MAX} defined in <limits.h> should always be used to learn about the limits on the number of scatter/gather elements that
can be processed in one call, instead of assuming a fixed value.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
