Print the buffer passed to the read function as a string (on read's return) for process 6312 ( running 3000pc-fifo, won't work on 3000pc-rendezvous): Report on the string passed to pick_word() on its return: Follow the instructions in the previous question to get it working with sudo. Note these assume you unpacked the 3000pc.zip in the Documents folder. You can learn more about trace from its man page.
Here are some example trace commands to play with. To do this, run sudo visudo and append :/usr/share/bcc/tools to the secure_path string on line 12. To get trace working with sudo, we need to modify the secure_path setting in /etc/sudoers. In order to use trace, it needs to be run with root privileges. We will be covering exactly how it works in an upcoming tutorial. For now, you can think of trace as a useful alternative to programs like gdb. In the next question, you will be playing around with trace from bcc-tools. Do you notice any difference in the system calls each program makes? Repeat the above experiment, this time running each program under strace (with the -f flag to trace children too). 
Do they behave the same way? Do you notice any differences? Run both programs with the same arguments of your choice.The number of events to consume before the consumer sleeps for 1 second.
The number of events to produce before the producer sleeps for 1 second. Note that these programs take 3 arguments each:. #Producer and consumer pthread c download#
Download 3000pc.zip, unpack, and run make to compile 3000pc-fifo and 3000pc-rendezvous.

The class VM has this already installed on other systems, you'll have to install it yourself.
Make sure you system has the a recent version of bcc-tools installed. 3 C: Producer/Consumer with Shared Memory.
