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.
