Get host ip and port from command arguments. If only one argument has * been provided it must be in the form of 'ip:port', elsewhere * the first argument must be the ip and the second one the port. * If host and port can be detected, it returns 1 and it stores host and * port into variables referenced by'ip_ptr' and 'port_ptr' pointers, * elsewhere it returns 0. */

 * port into variables referenced by'ip_ptr' and 'port_ptr' pointers,
 * elsewhere it returns 0. */
