LlLinksetDataDelete

Summary: llLinksetDataDelete, llLinksetDataDeleteProtected

The llLinksetDataDelete and llLinksetDataDeleteProtected functions erases a name:value pair from the linkset's datastore.

When this function successfully removes a name:value pair a linkset_data event is triggered in all scripts running in the linkset with an action of LINKSETDATA_DELETE and the name parameter set to the name that was removed. The value parameter in the event is set to an empty string.

Function: integer llLinksetDataDelete( string name );

The llLinksetDataDeleteProtected function erases a protected name:value pair from the linkset's datastore.
Returns an integer success or failure code.

• string	pass	–	A pass phrase previously used to protect the name:value pair.

Constant		Description
LINKSETDATA_OK	0	The name:value pair was written to the datastore.
LINKSETDATA_EMEMORY	1	A name:value pair was too large to write to the linkset datastore.
LINKSETDATA_ENOKEY	2	The name supplied to llLinksetDataWrite was empty.
LINKSETDATA_EPROTECTED	3	The name:value pair has been protected from overwrite in the linkset's datastore.
LINKSETDATA_NOTFOUND	4	The named key could not be found in the linkset's datastore when attempting to delete it.
LINKSETDATA_NOUPDATE	5	The name:value stored in the linkset was not changed by the write operation because the value stored matches the value written.

Caveats

If the name does not exist or the pass does not match, no event is triggered.
