apt-get remove libcurl4-openssl-dev:amd64
apt-get install xviewg-dev:i386 libcurl4-openssl-dev:i386 build-essential gcc-multilib
rm -f /etc/apt/sources.list.d/wfdb-tmp.list
./install-wave32 -q
apt-get remove libcurl4-openssl-dev:i386

#include <stdio.h>
#include <wfdb/wfdb.h>

main()
{
    int i;
    WFDB_Sample v[2];
    WFDB_Siginfo s[2];

    if (isigopen("100s", s, 2) < 2)
        exit(1);
    for (i = 0; i < 10; i++) {
        if (getvec(v) < 0)
            break;
        printf("%d\t%d\n", v[0], v[1]);
    }
    wfdbquit();
    exit(0);
}

Compile it using following command:

1
gcc -o psamples psamples.c -lwfdb

Run it:

1
./psamples

Then you can view the outputs as below:
