    system() asks for password


    I'm passing a command to system in this fasion:
    sprintf(command, "curl -A SAMPLE-DOWNLOADER -url \"\" > output.tmp\n", username, password );
    system (command);
    When i run this is a terminal window, i get asked to enter a password. Hitting enter lets me continue, but i need to do it without a password getting asked. any way i can do this?

    thanx, PRTSoft

    why are you passing a username and password variables to sprintf() after your format string? there arent any conversion specifiers in it
    hello, internet!

    Look at other ways in which curl allows you to specify username/password information
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    sorry i changed the text, in the original code block from what i had. here is what i HAVE:
     sprintf(command, "curl -A SAMPLE-DOWNLOADER -url \""
    "?version=2.0&UserID=%s&Pass=%s\" > sermonlist.tmp\n", 
    username, password );
    this isn't a form. I am reverse enginering (with permission to do a port) a client that downloads sermon MP3s from this is what it sends: =password

    this supplies a list of sermons that were selected on the main site.
    so i used sprintf *in hindsight maybe strcpy would have been better) to put the username and password in the URL.

    If there is a better faster way to do it, i'm all ears.
