acl_get_entry
() function is a POSIX.1e call that
retrieves a descriptor for an ACL entry specified by the argument
entry_d within the ACL indicated by the argument
acl.
If the value of entry_id is
ACL_FIRST_ENTRY
, then the function will return in
entry_p a descriptor for the first ACL entry within
acl. If a call is made to
acl_get_entry
() with entry_id
set to ACL_NEXT_ENTRY
when there has not been either
an initial successful call to acl_get_entry
(), or a
previous successful call to acl_create_entry
(),
acl_delete_entry
(),
acl_dup
(), acl_from_text
(),
acl_get_fd
(),
acl_get_file
(),
acl_set_fd
(),
acl_set_file
(), or
acl_valid
(), then the result is unspecified.
acl_get_entry
() function successfully obtains an
ACL entry, a value of 1 is returned. If the ACL has no ACL entries, the
acl_get_entry
() returns a value of 0. If the value of
entry_id is ACL_NEXT_ENTRY
and
the last ACL entry in the ACL has already been returned by a previous call to
acl_get_entry
(), a value of 0 will be returned until a
successful call with entry_id of
ACL_FIRST_ENTRY
is made. Otherwise, a value of -1 will
be returned and the global variable errno will be set to
indicate the error.
acl_get_entry
() fails if:
EINVAL
]ACL_FIRST_ENTRY
nor
ACL_NEXT_ENTRY
