Done...

First thought: is the fopen() working?

[dwhitney67]

This little puppy needs to point to some valid memory location within the program space; not just dangle.

lgfle is the logfile containing output of netstat -p command that would be passed from the shell...

It's use in the fscanf() is causing your app to "barf".

What dwhitney means is that lgfle1 = (null);

fscanf() runs successfully, but never passes any data to lgfile1 because it is not pointing to any memory.

edit:
Also, correct me if I'm wrong, but wouldn't fscanf only return the first word in the logfile? As it should stop after the first bit of whitespace is found.

There's no guarantee that this is the case; lgfle1 could be pointing anywhere. I bet it's pointing to an address (perhaps 0x00) that's outside the program space, thus causing the app to crash.

I have sorted out the problem. Actually we would have to use fgetc instead of fscanf to store complete data of file in lgfle.
