Function: integer llGetInventoryPermMask( string item, integer category );


0.0	Forced Delay
10.0	Energy

Returns a bit field (an integer) of the requested permission category for the inventory item

• string	item	–	an item in the inventory of the prim this script is in
• integer	category	–	MASK_* flag

Category		Description
MASK_BASE	0	The base permissions.
MASK_OWNER	1	Current owner permissions.
MASK_GROUP	2	Active group permissions.
MASK_EVERYONE	3	Permissions everyone has.
MASK_NEXT	4	Permissions the next owner will have.
MASK_COMBINED	16	Include object inventory contents when calculating perms. Combine with other mask flags, for instance MASK_OWNER\|MASK_COMBINED

Permissions	Value	Description
PERM_ALL	0x7FFFFFFF	Move/Modify/Copy/Transfer permissions
PERM_COPY	0x00008000	Copy permission
PERM_MODIFY	0x00004000	Modify permission
PERM_MOVE	0x00080000	Move permission
PERM_TRANSFER	0x00002000	Transfer permission

Caveats

If item is missing from the prim's inventory then an error is shouted on DEBUG_CHANNEL.
Note that including the MASK_COMBINED bit does not impact the output of this function, as the combined permissions are the only accessible permissions for inventory items.

Examples

if ((permsYouHave & permsYouWant) == permsYouWant)
    llSay(PUBLIC_CHANNEL, "You have the perms you want.");
else
    llSay(PUBLIC_CHANNEL, "You don't have the perms you want.");

integer ownerPerms = llGetInventoryPermMask("inventory item name goes here", MASK_OWNER);
integer copyAndModPerms = PERM_COPY | PERM_MODIFY;

if ((ownerPerms & copyAndModPerms) == copyAndModPerms)
    llSay(PUBLIC_CHANNEL, "Owner has copy & modify perms.");
else
    llSay(PUBLIC_CHANNEL, "Owner does not have copy & modify perms.");

string getPermsAsReadableString(integer perm)
{
    integer fullPerms = PERM_COPY | PERM_MODIFY | PERM_TRANSFER;
    integer copyModPerms = PERM_COPY | PERM_MODIFY;
    integer copyTransPerms = PERM_COPY | PERM_TRANSFER;
    integer modTransPerms = PERM_MODIFY | PERM_TRANSFER;
 
    string output = " perms: ";

    if ((perm & fullPerms) == fullPerms)
        output += "full";
    else if ((perm & copyModPerms) == copyModPerms)
        output += "copy & modify";
    else if ((perm & copyTransPerms) == copyTransPerms)
        output += "copy & transfer";
    else if ((perm & modTransPerms) == modTransPerms)
        output += "modify & transfer";
    else if ((perm & PERM_COPY) == PERM_COPY)
        output += "copy";
    else if ((perm & PERM_TRANSFER) == PERM_TRANSFER)
        output += "transfer";
    else
        output += "none";

    //  Remember, items in Second Life must have either
    //  PERM_COPY or PERM_TRANSFER when "talking about"
    //  owner perms or perms for next owner.

    return  output;
}

default
{
    state_entry()
    {
        string inventoryItemName = "inventory item name goes here";

        integer basePerms      = llGetInventoryPermMask(inventoryItemName, MASK_BASE);
        integer ownerPerms     = llGetInventoryPermMask(inventoryItemName, MASK_OWNER);
        integer nextOwnerPerms = llGetInventoryPermMask(inventoryItemName, MASK_NEXT);
        integer groupPerms     = llGetInventoryPermMask(inventoryItemName, MASK_GROUP);
        integer everyonePerms  = llGetInventoryPermMask(inventoryItemName, MASK_EVERYONE);

        llSay(0, "/me [" + inventoryItemName
            + "]: base" + getPermsAsReadableString(basePerms));
        llSay(0, "/me [" + inventoryItemName
            + "]: owner" + getPermsAsReadableString(ownerPerms));
        llSay(0, "/me [" + inventoryItemName
            + "]: next owner" + getPermsAsReadableString(nextOwnerPerms));
        llSay(0, "/me [" + inventoryItemName
            + "]: group" + getPermsAsReadableString(groupPerms));
        llSay(0, "/me [" + inventoryItemName
            + "]: everyone" + getPermsAsReadableString(everyonePerms));
    }
}

To test for the opposite (e.g. to see if something is NOT copy):

    if (!(PERM_COPY & llGetInventoryPermMask(myitem, MASK_OWNER)))
        llSay(PUBLIC_CHANNEL, "/me [" + myitem + "]: owner doesn't have copy perms.");

To remind the next owner what permissions to set before selling on choose which need to be set;

CheckPerms()
{        
    string item = llGetScriptName();
    integer nextOwnerPerms = llGetInventoryPermMask(item, MASK_NEXT);

    if(PERM_COPY & nextOwnerPerms)
        llOwnerSay("Set no copy");

    if(PERM_MODIFY & nextOwnerPerms)
        llOwnerSay("Set no mod");

    if(PERM_TRANSFER & nextOwnerPerms)
        llOwnerSay("Set no transfer");
}
 
default
{
    on_rez(integer start_param)
    {
        llResetScript();
    }

    state_entry()
    {
        if(llGetOwner() != llGetInventoryCreator(llGetScriptName()))
            CheckPerms();
    }
}

Notes

In effect, the perms for articles published on this Wiki are PERM_COPY and PERM_TRANSFER until you log in, then PERM_MODIFY, PERM_MOVE, PERM_COPY and PERM_TRANSFER.
The default perms of a newly created script are: Base = PERM_ALL, Owner = PERM_ALL, Next = PERM_MOVE or PERM_TRANSFER, Group = 0 (none), Everyone = 0 (none). These perms are the same, no matter if the script is created in user inventory or in an object.
- However, an option in the Preferences > Advanced menu allows to set the Default Creation Permissions of all items that can be created or uploaded in-world.
