## DESCRIPTION

The **acl\_free**() call allows the freeing of ACL working space, such as is allocated by [acl\_dup(3)](/acl_dup/3.md), or [acl\_from\_text(3)](/acl_from_text/3.md).

## RETURN VALUES

The **acl\_free()** function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate the error.

## ERRORS

- \[EINVAL\]

  The value of the *obj\_p* argument is invalid.
