    getting last element in file

    Hi, i am trying to get the last structure in a binary file and am using
    fseek(t,sizeof(struct man),SEEK_END) but its not working. I have tried substituting SEEK_END - sizeof(struct man) .
    fseek(t,sizeof(struct man),SEEK_END-sizeof(struct man)) still didnt work

    You don't want to read the data? To me, "get" equals "read". So I'm confused.

    He first has to seek to the appropriate position within the file prior to the read operation. It's been a long time since I've used fseek but wouldn't it be something like:
    Code:
    fseek(t,-sizeof(struct man),SEEK_END);
    I think that would go sizeof(struct man) bytes backwards (towards the start of the file) from the end of the file... which is what you'd want. You'd then be able to do an fread call.
