acl_clear_perms(acl_permset_t permset_d);

The acl_clear_perms() function clears all permissions from the permission set referred to by the argument permset_d.

Any existing descriptors that refer to permset_d shall continue to refer to that permission set.

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

If any of the following conditions occur, the acl_clear_perms() function returns -1 and sets errno to the corresponding value:
The argument permset_d is not a valid descriptor for a permission set within an ACL entry.
