Function: integer llClearLinkMedia( integer link, integer face );

Clears (deletes) the media and all params from the given face on the linked prim(s).
Returns a status (an integer) that is a STATUS_* flag which details the success/failure of the operation.

• integer link Link number (0: unlinked, 1: root prim, >1: child prims and seated avatars) or a LINK_* flag
• integer face face number

Flag Description
LINK_ROOT 1 refers to the root prim in a multi-prim linked set[1]
Flag Description
LINK_THIS -4 refers to the prim the script is in

Success/Failure Flags Description
STATUS_OK 0 Result of function call was success
STATUS_MALFORMED_PARAMS 1000 Function was called with malformed parameters
STATUS_TYPE_MISMATCH 1001 Argument(s) passed to function had a type mismatch
STATUS_BOUNDS_ERROR 1002 Argument(s) passed to function had a bounds error
STATUS_NOT_FOUND 1003 Object or other item was not found
STATUS_NOT_SUPPORTED 1004 Feature not supported
STATUS_INTERNAL_ERROR 1999 An internal error occurred

Link Numbers

Each prim that makes up an object has an address, a link number. To access a specific prim in the object, the prim's link number must be known. In addition to prims having link numbers, avatars seated upon the object do as well.

  • If an object consists of only one prim, and there are no avatars seated upon it, the (root) prim's link number is zero.
  • However, if the object is made up of multiple prims or there is an avatar seated upon the object, the root prim's link number is one.

When an avatar sits on an object, it is added to the end of the link set and will have the largest link number. In addition to this, while an avatar is seated upon an object, the object is unable to link or unlink prims without unseating all avatars first.

Counting Prims & Avatars

There are two functions of interest when trying to find the number of prims and avatars on an object.

integer GetPrimCount() { //always returns only the number of prims
    if(llGetAttached())//Is it attached?
        return llGetNumberOfPrims();//returns avatars and prims but attachments can't be sat on.
    return llGetObjectPrimCount(llGetKey());//returns only prims but won't work on attachments.
See llGetNumberOfPrims for more about counting prims and avatars.


If a script located in a child prim erroneously attempts to access link 0, it will get or set the property of the linkset's root prim. This bug (BUG-5049) is preserved for broken legacy scripts.

   ll*LinkMedia functions do not work with LINK_* flags


  1. ^ LINK_ROOT does not work on single prim objects. Unless there is an avatar sitting on the object.
