ข้อผิดพลาดการแบ่งส่วนในซ็อกเก็ต

ฉันมีปัญหาที่แปลกประหลาดมาก รหัสของฉันทำงานอย่างถูกต้องครั้งหนึ่ง จากนั้นฉันก็ปิดเทอร์มินัลใน linux และเปิดใหม่อีกครั้งเพื่อเรียกใช้โค้ด แต่ตอนนี้ฉันได้รับข้อผิดพลาดในการแบ่งส่วน ไม่สามารถถอดรหัสสิ่งที่เกิดขึ้นได้แน่ชัด...ความช่วยเหลือใด ๆ ที่จะได้รับการชื่นชม

รหัสของฉัน:

#include <sys/socket.h>
