interprocess communication mechanism.

1. Describe a way to use mmap and signals to construct an interprocess communication mechanism.

2. A file is mapped in using the following mmap system call: mmap(65536, 32768, READ, FLAGS, fd, 0) Pages are 8 KB. Which byte in the file is accessed by reading a byte at memory address 72,000?

3. After the system call of the previous problem has been executed, the call munmap(65536, 8192) is carried out. Does it succeed? If so, which bytes of the file remain mapped? If not, why does it fail?
