[zyc_glboy]

RT
code：

    rc = gethostname(hname, sizeof(hname));
    if (rc == -1) {
        printf("%s: failed in gethostname,lien=%d,%s\n", __FUNCTION__, __LINE__, strerror(errno));
        return -1; 
    }   
    printf("hostname is %s\n", hname);

    ht = gethostbyname(hname);
    if (ht == NULL) {
        printf("%s: failed in gethostbyname,line=%d,%s\n", __FUNCTION__, __LINE__, strerror(h_errno));
        return -1; 
    }

请高手指教~~~~~~
