    mysql_close(), mysql_init, mysql_real_connect










  1. View Hint View Answer Discuss in Forum

    It is not necessary that every Application Programming Interface call would return a value. For example, the client routine named ‘mysql_close()’ returns void, that is, it does not return a value.

  1. Which of the following use ‘NULL’ to indicate failure?
    mysql_init(), mysql_real_connect()










  1. View Hint View Answer Discuss in Forum

    Correct Option: B

    Both of the client library routines named ‘mysql_init()’ and ‘mysql_real_connect()’ return a pointer to the connection handler in order to indicate success and NULL to indicate failure.
