Advanced Operating Systems
Enhance the shell from p3 to support the new facilities described below.
Enhance the shell's capabilities with support for two new builtin commands
named shmalloc and shmdel:
shmalloc SHM_NAME SHM_SIZE_IN_MB
makes a posix-compatible shared memory area available for subsequent
programs to use (mmap and shm_open); note that multiple processes
can share the area simultaneously
shmdel SHM_NAME
removes the shared memory area (shm_unlink)
Submitting the project for grading:
The project should compile and link as p4.
You should turnin a tar file containing all of the required files.
To build the project, I will cd to my directory containing your files
and simply type:
rm -rf p4
rm -rf *.o
make
