    Red face Trailing characters after strncpy

    Hi Guys,
    i have searched but could not find any previouse solution.
    I'm coping n characters, but after sending the final to the
    printer, i get some trailing characters like c@xn after the
    true result.
    example
    str[]="mynameissomename";
    strncpy(name,str,4);

    when i send this to
    fprintf(prn_ptr,"%s",name);
    the result is mynam@cxn on the printer.
    Any help will do

    thanks

    Your code is incomplete. What is "name"? Without seeing your exact code, one can only speculate. I'm assuming name is a 4 byte array. As such, it's not null terminated, so your print statement displays until it hits a null (at some random point in memory).

    Hope is the first step on the road to disappointment.
