Typo in example code of process_vm_readv

[Ville Ylenius <ville-xG8NWnMrmhjR7s880joybQ@public.gmane.org>]

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!
