Preemptive priority task scheduling C code?

Preemptive priority task scheduling allows higher-priority tasks to interrupt lower-priority ones. In C, you can implement this using a priority queue to manage tasks based on their priority levels. Below is a simple example using a struct for tasks and a basic loop to simulate scheduling:

<code class="language-c">#include <stdio.h>
#include <stdlib.h>
typedef struct Task { int id; int priority; } Task;
void schedule(Task tasks[], int n) { // Simple scheduling loop for (int i = 0; i < n; i++) { // Here you would implement preemption logic // For example, sort tasks based on priority and execute the highest priority task printf("Executing Task %d with priority %d\n", tasks[i].id, tasks[i].priority); } }
int main() { Task tasks[] = {{1, 2}, {2, 1}, {3, 3}}; int n = sizeof(tasks) / sizeof(tasks[0]); schedule(tasks, n); return 0; }
</code>

This code is a simplified example; a complete implementation would require more sophisticated handling of task states and preemption logic.
