WebMay 12, 2023 · Understanding the Critical-Section Before discussing semaphore and mutex, let us understand the critical-section problem. Let us assume that we have a system that contains n processes. Each of these processes has a segment of code in which the process may perform a common variable update, a table update, or write into a file.

WebApr 5, 2017 · 1 I was reading a bit of Mutex and semaphore. I have piece of code int func () { i++; return i; } i is declared somewhere outside as a global variable. If i create counting semaphore with count as 3 won't it have a race condition? does that mean i should be using a binary semaphore or a Mutex in this case ?

WebThe basic difference between semaphore and mutex is that semaphore is a signalling mechanism i.e. processes perform wait () and signal () operation to indicate whether they are acquiring or releasing the resource, while Mutex is locking mechanism, the process has to acquire the lock on mutex object if it wants to acquire the resource.

Semaphore (programming) - Wikipedia
https://en.wikipedia.org/wiki/Semaphore_(programming)
WebImportant observations When used to control access to a pool of resources, a semaphore tracks only how many resources are free; it does not keep track of which of the resources are free. Some other mechanism (possibly involving more semaphores) may be required to select a particular free resource.
