Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
int
acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm)
DESCRIPTION
The acl_delete_perm() function deletes the permission contained in the
argument perm from the permission set referred to by the argument
permset_d. An attempt to delete a permission that is not contained in the
permission set is not considered an error.
Any existing descriptors that refer to permset_d continue to refer to
that permission set.
RETURN VALUE
The acl_delete_perm() function returns the value 0 if successful; other
wise the value -1 is returned and the global variable errno is set to in
dicate the error.
ERRORS
If any of the following conditions occur, the acl_delete_perm() function
returns -1 and sets errno to the corresponding value:
[EINVAL] The argument permset_d is not a valid descriptor for a per
mission set within an ACL entry.
The argument perm does not contain a valid acl_perm_t val
ue.
