acl_add_perm(acl_permset_t permset_d, acl_perm_t perm);
Описание (Description)
The acl_add_perm() function adds the permission contained in the
argument perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE) to the
permission set referred to by the argument permset_d. An attempt
to add a permission that is already 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.
Возвращаемое значение (Return value)
The acl_add_perm() function returns the value 0 if successful;
otherwise the value -1 is returned and the global variable errno is
set to indicate the error.
Ошибки (Error)
If any of the following conditions occur, the acl_add_perm()
function returns -1 and sets errno to the corresponding value:
[EINVAL] The argument permset_d is not a valid descriptor
for a permission set within an ACL entry.
The argument perm does not contain a valid
acl_perm_t value.
