AUTOSAR C Runnable Implementation
/* AUTOSAR Runnable Implementation */
#include "Rte_MyComponent.h"
void MyRunnable(void)
{
/* Example: read input port, process, write output port */
int input = Rte_IRead_MyRunnable_InputPort();
int result = input * 2;
Rte_IWrite_MyRunnable_OutputPort(result);
}
C implementation of an AUTOSAR Runnable defined in ARXML, adhering to safety-critical C coding guidelines.
