Fork with Semaphores and mmap

Simple Parent-Child Orchestration Example using Fork to create a Childprocess.

To run this program, run:

gcc fork_semaphore_mmap.c -o fsm -lpthread

and then:

./fsm

N Producer and M Consumer Problem

See: https://www.cs.fsu.edu/~baker/realtime/restricted/notes/prodcons.html

Producer-Consumer Problem

• One or more threads generate data and put it into a buffer
• One or more threads take data items from the buffer, one at time
• Only one producer or consumer may access the buffer at any one time
• Variants, of increasing difficulty:
  • Single producer & single consumer
  • Multiple producers & single consumer
  • Multiple producers & multiple consumers

Multithreading (N+M) with N Producer and M Consumer using Semaphores, Mutex and Circular Buffer

To run this program, run:

gcc producer_consumer.c -o prodcon -lpthread

and then:

./prodcon

To test this program, run:

gcc producer_consumer.c -o prodcon -lpthread && ./prodcon > tests/test.txt && node tests/producer_consumer.js tests/test.txt

You will need Node.js for the test.
