Имя (Name)

acl_add_perm — add a permission to an ACL permission set

---

Библиотека (Library)

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

Синопсис (Synopsis)

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

     int
     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.
