我想从结构统计显示我的两个属性
struct stat { dev_t st_dev; /* ID of device containing file */ ino_t st_ino; /* inode number */ mode_t st_mode; /* protection */ 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; /* blocksize for file system I/O */ blkcnt_t st_blocks; /* number of 512B blocks allocated */ time_t st_atime; /* time of last access */ time_t st_mtime; /* time of last modification */ time_t st_ctime; /* time of last status change */ };
这里是我的代码，我尝试显示最后一次访问和上次修改文件夹/文件的最后一次
struct tm *time; char buffer[200]; time = localtime(file_info.st_atime); strftime(buffer, sizeof(buffer), "%d.%m.%Y %H:%M:%S", time); printf("%s\n", buffer); time = localtime(file_info.st_mtime); strftime(buffer, sizeof(buffer), "%d.%m.%Y %H:%M:%S", time); printf("%s\n", buffer);
我想显示像人类可读的时间和date，如15.03.1952 23:11:34文件夹/文件信息已被修改或在Linux中访问
这在风格上偏离了代码，但也许有帮助？
#include <time.h> #include <stdio.h> #include <sys/stat.h> #include <stdlib.h> char* formatdate(char* str, time_t val) { strftime(str, 36, "%d.%m.%Y %H:%M:%S", localtime(&val)); return str; } int main() { int errno; const char* filename; filename = "stat.c"; errno = 0; struct stat *file_info = malloc(sizeof(struct stat)); if (lstat(filename, file_info) != 0) { perror("Error"); exit(1); } char date[36]; printf("Access: %s\n", formatdate(date, file_info->st_atime)); printf("Modify: %s\n", formatdate(date, file_info->st_mtime)); printf("Change: %s\n", formatdate(date, file_info->st_ctime)); free(file_info); return 0; }
char buffer[200]; printf("Access : %s\n", formatdate(buffer, file_info.st_atime)); printf("Modify : %s\n", formatdate(buffer, file_info.st_mtime)); printf("\n\n"); char *formatdate(char *buff, time_t val) { strftime(buff,200, "%d.%m.%Y %H:%M:%S", localtime(&val)); return buff; }
这是我正在寻找的答案，再次感谢。
试试这个： printf("%s", asctime(localtime(&buffer.st_mtime)));
