Standard C Library (libc, -lc)
acl_get_brand_np(acl_t acl, int *brand_p);
The acl_get_brand_np() function is a non-portable call that returns the
ACL brand for the ACL acl. Upon successful completion, the location
referred to by the argument brand_p will be set to the ACL brand of the
Branding is an internal mechanism intended to prevent mixing POSIX.1e and
NFSv4 entries by mistake. It's also used by the libc to determine how to
print out the ACL. The first call to function that is specific for one
particular brand - POSIX.1e or NFSv4 - "brands" the ACL. After that,
calling function specific to another brand will result in error.
The acl_get_brand_np() function returns the value 0 if successful; other‐
wise the value -1 is returned and the global variable errno is set to
indicate the error.
The acl_get_brand_np() function fails if:
[EINVAL] Argument acl does not point to a valid ACL.
