Re: FW: lseek

Hi Pete,

I followed Scott's examples but it got me nowhere. Hence my quest for help.

Emmanuel,

You may want to take a look at Scott Klements tutorial on IFS. Plenty of examples on working with files and doing what you are attempting to do.

Hi list,
I am trying to update an ifs file by using the c function lseek() for positioning and then write() to update the ifs file. I had no success so far.
The program created a text file and get populated with "Hello World". After the file is populated then its closed. I re-open the file and read the contend of the file. I then attempt to change the read data by doing the lseek first and updating the file via write(). Any ideas on how to achieve that?
A list of the code is attached
