    Character matching in C


    Hi,
    I'm currently trying to make a parallel port device driver under linux, written in c.

    The problem is, to get started i need to write some code that will open and read the pattern file (That i have - File name: rw_buf.pat).
    At the top of the file there is 6 lines all beginning with 'in' or 'out'.
    These are as follows:
    in reset;
    in clk;
    in ready;
    in read_write;
    out oe;
    out we;


    The program will need to read those lines and match which ones are in and which ones are out . And the data to be stored somewhere, which will be used at a later date to set the pins to in or out.

    So for starters i need to be able to identify the in and out pins and print to screen details of each.

    I would be very grateful for any advice anyone could give me..

    Cheers Guys

    Use this schematic:

    Another handy article for you:

    Remember, Google is your friend.

    [edit]

    Never mind, I just read your question again. Use the strstr() function to do your string searching.
