How To Define and Use your own CODE_REGION ! Example: static void __code_region_example_on_enter(void *obj_ptr, void *local_ptr) { printf("-------enter-------\r\n"); } static void __code_region_example_on_leave(void *obj_ptr,void *local_ptr) { printf("-------leave-------\r\n"); } const static i_code_region_t __example_code_region = { .OnEnter = __code_region_example_on_enter, .OnLeave = __code_region_example_on_leave, }; void main(void) { ... code_region(&__example_code_region, NULL){ printf("\tbody\r\n"); } ... } Output: ----—enter----— body ----—leave----— ! Note How to use code_region() ! Syntax: ! code_region(<Address of i_code_region_t obj>, <Object Address>) { ! //! put your code here ! } ! ! <Address of i_code_region_t obj>: this can be NULL, if so, ! DEFAULT_CODE_REGION_NONE will be used. ! ! <Object Address>: it is the address of the object you want to pass to ! your OnEnter and OnLeave functions. It can be NULL ! ! A local object will be generated from users' stack, the size is specified ! by i_code_region_t.chLocalSize. The address of this local object will ! be passed to your OnEnter and OnLeave functions. You can use it to ! store some local status. ! ! ! ! DEFAULT_CODE_REGION_ATOM_CODE //!< interrupt-safe region ! DEFAULT_CODE_REGION_NONE //!< do nothing !
