Question

How to retrieve a file/folder’s properties in C, particularly in Linux?

I need info about date created, last modified, isDirectory or isFile, permission, ownership and size.

Thanks.

You most likely need the stat() function.

Example:

struct stat attr;
stat("/home/crazyfffan/foo.txt", &attr);

printf("Size: %u\n", (unsigned)attr.st_size);
printf("Permissions: %o\n", (int)attr.st_mode & 07777);
printf("Is directory? %d\n", attr.st_mode & ST_ISDIR);

etc.
