acl_entries - Man Page

Linux Access Control Lists library (libacl, -lacl).

#include <sys/types.h>
#include <acl/libacl.h>

int
acl_entries(acl_t acl);

The acl_entries() function returns the number of ACL entries that are contained in the ACL referred to by the argument acl.

The acl_entries() function returns the number of entries in acl if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

If any of the following conditions occur, the acl_entries() function returns -1 and sets errno to the corresponding value:

[EINVAL]

The argument acl is not a valid pointer to an ACL.

This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned).
