Web• Shared-memory solution to bounded-buffer problem (Chapter 4) allows at most n – 1 items in buffer at the same time. A solution, where all N buffers are used is not simple. … WebOct 30, 2016 · The bounded buffer using semaphores in C. The following is the code I have so far. The program uses a buffer shared between two processes, a producer and a consumer. The producer reads characters from a file and places them in the buffer. The consumer reads each item from the buffer and prints the characters onto the screen.
