     "3.) mmap(): The mmap() system call is used to allocate anonymous memory in page sized increments into a contiguous set of virtual pages or map the contents of a file segment into a set virtual pages. The use is “address=mmap(arguments, …)” where the arguments instruct whether to allocate anonymous memory or map a file section and address is the page aligned virtual address of the newly allocated memory.\n",
