Typo in example code of process_vm_readv

[Ville Ylenius <ville@xxxxxxxxxxx>]

Hi,

there is a small typo in the example code of the man page of 
"process_vm_readv" 
(http://man7.org/linux/man-pages/man2/process_vm_readv.2.html):

       #include <sys/uio.h>

       int
       main(void)
       {
           struct iovec local[2];
           struct iovec remote[1];
           char buf1[10];
           char buf2[10];
           ssize_t nread;
           pid_t pid = 10;             /* PID of remote process */

           local[0].iov_base = buf1;
           local[0].iov_len = 10;
           local[1].iov_base = buf2;
           local[1].iov_len = 10;
           remote[0].iov_base = (void *) 0x10000;
           remote[1].iov_len = 20;                     /**** <---- TYPO: 1 --> 0 ****/

           nread = process_vm_readv(pid, local, 2, remote, 1, 0);
           if (nread != 20)
               return 1;
           else
               return 0;
       }


There is no two objects in "remote"-array so program corrupts other 
variables memory.

Please change

remote[1].iov_len = 20;

to

remote[0].iov_len = 20;

Thank you!
