    --------------------------------------------------------------------------------------------------------------------------------

    /* make_contact.c */

    #include "cnaiapi.h"

    /*-----------------------------------------------------------------------
    * make_contact - open a new TCP connection to the specified IP address
    * (c) and port e(a).
    *-----------------------------------------------------------------------
    */
    connection
    make_contact(computer c, appnum a)
    {
    struct sockaddr_in sockaddr;
    int sock;

    cnaiapi_init();

    sock = socket(PF_INET, SOCK_STREAM, 0);
    if (sock < 0)
    return -1;

    (void) memset(&sockaddr, 0, sizeof(struct sockaddr_in));

    sockaddr.sin_family = AF_INET;
    sockaddr.sin_port = htons(a);
    sockaddr.sin_addr.s_addr = c;

    if (connect(sock, (struct sockaddr *) &sockaddr, sizeof(struct sockaddr_in)) < 0) {
    #if defined(LINUX) || defined(SOLARIS)
    close(sock);
    #elif defined(WINDOWS)
    closesocket(sock);
    #endif
    return -1;
    }
    return sock;

    It opens a new TCP connection to a specific IP address and port.
