Hi,
I am Rohan Rajak a 3rd year computer science student at IIT Kharagpur,
(India).
My interest lies in System Programming. I have taken courses like operating
system, computer networks etc. And I am familiar with multithreaded and
shell programming.
I am looking forward to work in comprehensive test suite project of strace
in GSOC 2017. I have gone through most of the conversation in the mailing
list (recent and archive), I know I took time to get started as I was
trying hard to understand it.
I have implemented an exit and an error message in the file test/skodic.c
to demonstrate races.
I have exited with -1 when the file descriptor haven't found any file.
git send-email is not working as I am in a private network.
So i am attaching the patch below
please review my patch
