How to sync tasks using FreeRTOS library?

Question

I have 5 tasks(function) in 5 different which are running simultaneously. I want to implement like any function start running then other function should not run until the function completes its process. I want to implement using FreeRTOS. Example.

• foo1.c ->Task1
• foo2.c ->Task2
• foo3.c ->Task3
• foo4.c ->Task4
• foo5.c ->Task5

It sounds like you need a mutex. Each task acquires the mutex when they start running, and release it when they are done. When any of the tasks is running, others are blocked on the mutex.
