What is `@`???? – iBug Feb 02 '18 at 10:29

Note that in MacOS, `@` is a valid flag for the `ls` command to display a directory or file's extended attributes. – Sergio Feo Feb 02 '18 at 10:34

Not related to C language. Please don't use unrelated tags. – Gerhardh Feb 02 '18 at 12:07

This is MacOS specific I think. Maybe you want to take a look at the xattr command here. The number displayed by ls is the size in bytes of the attribute. The meaning of the value of a particular attribute is arbitrary (as is the set of extended attributes a file may have) and really depends on the attribute itself.
To be consistent with your question tags, you can also access extended attributes programatically from C by including sys/xattr.h.

This number means sizeof extended attribute in bytes.
You can get it by getxattr from sys/xattr.h
