Shmat jobs
I will need a developer for a c language project: He will have to master: - process: fork, getpid, wait, exit - files: functions of opening, writing, reading, closing and redirects dup dup 2 also fcntl - Inter processes communication: flock (), shmget (), shmat (), shmdt (), shmctl () but also the tubes - process synchronization: signals and semaphores contact me for more information

...from the shared buffer, it sends a signal to main process. Main process then enters a “C” in the monitoring table. When producer and consumer have copied the entire file1, consumer sends a signal to main process. Main process outputs the monitoring table. Implement the above in the UNIX environment using C. You may need system calls: signal, kill, pause, sleep, semget, semctl, semop, shmget, shmat, shmctl, etc. When sending signals, you should use the two signals defined for users: SIGUSR1 and SIGUSR2 for the producer and consumer respectively. Your code should be well documented so that others may read your code....

- Deliver a small Windows DLL programmed in C / C++. - The code to be transfered is a sample developed for Unix - Sample is < 100 lines of code using shmat function(ality)
...the shared memory. The consumer will remove items from the buffer and "consume" them. The queue will have a maximum capacity of 10 items. Fork should be used to create the two processes. (parent process: producer, child process: consumer) The shared memory should be created with shmget and will be deleted with shmdt. Also for the shared memory part, the following commands should be used: shmop, shmat, shmctl, ipcrm, ipcs) Semaphores will be used for the synchronization of the two processes (the commands sema_init, sema_destroy, sema_wait, sema_trywait and sema_post should be used). In the attached .zip file there is a .pdf that might help with some of the commands that should be used and a sample code file that roughly shows how the code should look like. ## Deliverab...
