Description

The acl_set_permset() function sets the permission set of the ACL entry indicated by the argument entry_d to the permissions contained in the argument permset_d.

Any ACL entry descriptors that refer to the entry containing the permission set referred to by permset_d shall continue to refer to those entries. Any ACL entry descriptors that refer to the entry referred to by entry_d shall continue to refer to that entry.

Return Value

The acl_set_permset() 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

If any of the following conditions occur, the acl_set_permset() function returns -1 and sets errno to the corresponding value:

[EINVAL]
The argument entry_d is not a valid descriptor for an ACL entry.

The argument permset_d is not a valid descriptor for a permission set within an ACL entry.
