NAME

4     acl_delete_perm — delete a permission from an ACL permission set
5

LIBRARY

7     Linux Access Control Lists library (libacl, -lacl).
8

SYNOPSIS

10     #include <sys/types.h>
11     #include <sys/acl.h>
12
13     int
14     acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm);
15

DESCRIPTION

17     The acl_delete_perm() function deletes the permission contained in the
18     argument perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE) from the permis‐
19     sion set referred to by the argument permset_d.  An attempt to delete a
20     permission that is not contained in the permission set is not considered
21     an error.
22
23     Any existing descriptors that refer to permset_d continue to refer to
24     that permission set.
25

RETURN VALUE

27     The acl_delete_perm() function returns the value 0 if successful; other‐
28     wise the value -1 is returned and the global variable errno is set to in‐
29     dicate the error.
30

ERRORS

32     If any of the following conditions occur, the acl_delete_perm() function
33     returns -1 and sets errno to the corresponding value:
34
35     [EINVAL]           The argument permset_d is not a valid descriptor for a
36                        permission set within an ACL entry.
37
38                        The argument perm does not contain a valid acl_perm_t
39                        value.
