Hi All.
We have deployed a simple C-application on an embedded-platform running Linux, and we spuriously observe file-corruption. In particular, there is an all-important "config" file, and some of its lines are lost spuriously.
Now, our application opens quite a few files on the file-systems, and one serial-port. During the course, if an error occurs, we simply "exit(1)" the binary, without any special code for closing any opened-file-descriptors.
I tested with "lsof", and confirmed that after binary exit, any open-file-descriptors are closed (automatically by kernel).
With this as the background, I revisit my question :: Is kernel-file-descriptor-auto-close exactly equal to explicit-file-descriptor-close?
Will be grateful for pointers; as of now, nightmares have begun striking me.
Thanks and Regards, Ajay
