- create a new ACL entry
Linux Access Control Lists library (libacl, -lacl).
Fn acl_create_entry acl_t *acl_p acl_entry_t *entry_p
function creates a new ACL entry in the ACL pointed to by the contents of the pointer argument
On success, the function returns a descriptor for the new
ACL entry via
This function may cause memory to be allocated. The caller should free any
releasable memory, when the new ACL is no longer required, by calling
as an argument.
If the ACL working storage cannot be increased in the current location,
then the working storage for the ACL pointed to by
may be relocated and the previous working storage is released. A pointer to
the new working storage is returned via
The components of the new ACL entry are initialized in the following ways: the
ACL tag type component contains ACL_UNDEFINED_TAG, the qualifier component
contains ACL_UNDEFINED_ID, and the set of permissions has no permissions
enabled. Any existing ACL entry descriptors that refer to entries in the ACL
continue to refer to those entries.
Rv -std acl_create_entry
If any of the following conditions occur, the
to the corresponding value:
- Bq Er EINVAL
is not a valid pointer to an ACL.
- Bq Er ENOMEM
The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
