需要用到的头文件 #include <sys/types.h> #include <sys/stat.h> #include <unistd.h> 定义stat结构体,stat包含 struct stat { dev_t st_dev; /* ID of device containing file */ ino_t st_ino; /* Inode number */ mode_t st_mode; /* File type and mode */ nlink_t st_nlink; /* Number of hard links */ uid_t st_uid; /* User ID of owner */ gid_t st_gid; /* Group ID of owner */ dev_t st_rdev; /* Device ID (if special file) */ off_t st_size; /* Total size, in bytes */ blksize_t st_blksize; /* Block size for filesystem I/O */ blkcnt_t st_blocks; /* Number of 512B blocks allocated */ /* Since Linux 2.6, the kernel supports nanosecond precision for the following timestamp fields. For the details before Linux 2.6, see NOTES. */ struct timespec st_atim; /* Time of last access */ struct timespec st_mtim; /* Time of last modification */ struct timespec st_ctim; /* Time of last status change */ #define st_atime st_atim.tv_sec /* Backward compatibility */ #define st_mtime st_mtim.tv_sec #define st_ctime st_ctim.tv_sec }; main() { 文件传入argv数组 将值传入结构体 打印结构体内容 }
