{{函数详情
|函数名 = Function: integer llGetInventoryPermMask( string item, integer category )
|参数= 参数：
*string item–an item in the inventory of the prim this script is in
*integer category–MASK_* flag
|返回值= 返回值：返回库存项的请求权限类别的位字段(整数)

|注意事项=
注意事项
*如果项目从prim的库存中丢失，那么在DEBUG_CHANNEL上会喊出一个错误。

|示例=
<pre>
if ((permsYouHave & permsYouWant) == permsYouWant)

</pre>
<pre>

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

</pre>
测试反义词(例如，看某物是否不是复制的):
<pre>
if (!(PERM_COPY & llGetInventoryPermMask(myitem, MASK_OWNER)))
llSay(PUBLIC_CHANNEL, "/me [" + myitem + "]: owner doesn't have copy perms.");
</pre>
提醒下一位业主在出售前设置哪些权限，选择哪些权限需要设置;
<pre>
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();
}
}
</pre>
