Re: IFS File Update

You can position to a particular byte of your file using the lseek() API

Once positioned, the write() API will overwrite bytes at that position (for the length specified on the call to write API)

Is that what you're asking? {There weren't actually any questions in your post.)

I need to update data in a stream file located in ths IFS (or on a QNTC

don't want to use any procedures that add a CRLF. I'm thinking of using
read() and write(), but I'm not sure how to handle the update. Probably
pretty simple. Thanks!
