CHAPTER 18 SERVICE CALLS

---

This chapter describes the service calls supported by the RI600V4.

18.1 Outline

The service calls provided by the RI600V4 are service routines provided for indirectly manipulating the resources (tasks, semaphores, etc.) managed by the RI600V4 from a processing program.

The service calls provided by the RI600V4 are listed below by management module.

- Task management functions

18.1.1 Method for calling service calls

The service calls can be calls by the same way as normal C-language function.

Note To call the service calls provided by the RI600V4 from a processing program, the header files listed below must be coded (include processing).

kernel.h: Standard header file

kernel_id.h System information header file, which is generated by the cfg600
