This allows you to extend the functionality of µC/OS-II as you will see shortly. The code for TaskStart() is shown in Listing 1.15.Control of the scheduler and access to these services is by means of the kernel’s application program interface (API). APIs differ from one RTOS to another, although there are some standards, like POSIX, but some characteristics are common to many RTOSes. One of those similarities is the function of blocking and non-blocking calls ... Each task-related control block represents one unit of work. Control blocks serve as vehicles for communication throughout z/OS. Such communication is possible because the structure of a control block is known to the programs that use it, and thus these programs can find needed information about the unit of work or resource. TCB or Task Control Blocks are data structures that reside in the RAM (Random Access Memory) and contain information about the status of each task. They are held in a block of memory and are accessible only by RTOS. Task Stack refers to the data defined in the program that resides in the RAM and is accessible by the stack pointer.task. h.
