LSL Wiki : llGetPermissions

integer llGetPermissions();

Returns which permissions have been granted. The return value will be a bitmask of the following values:

Constant:	Result	Allows
`PERMISSION_DEBIT`	Permission to take money from agent's account.	Use of `llGiveMoney`.
`PERMISSION_TAKE_CONTROLS`	Permission to take agent's controls.	Use of `llTakeControls` and `llReleaseControls`
`PERMISSION_TRIGGER_ANIMATION`	Permission to trigger animation on agent.	Use of `llStartAnimation` and `llStopAnimation`.
`PERMISSION_ATTACH`	Permission to attach/detach from agent.	Use of `llAttachToAvatar` and `llDetachFromAvatar`
`PERMISSION_CHANGE_LINKS`	Permission to change links.	Use of `llCreateLink`, `llBreakLink`, and `llBreakAllLinks`
`PERMISSION_TRACK_CAMERA`	Permission to track the agent's camera position and rotation	Use of `llGetCameraPos` and `llGetCameraRot`
`PERMISSION_CONTROL_CAMERA`	Permission to control the agent's camera	Use of `llSetCameraParams` and `llClearCameraParams`

To compare the resulting number to these constants, remember that it is necessary to use bitwise operators! That means doing if (llGetPermissions() & PERMISSION_ATTACH), not if (llGetPermissions() == PERMISSION_ATTACH). The latter may work some of the time, but not in all cases.

Example:

integer perm = llGetPermissions();

if (perm & PERMISSION_DEBIT) // using & is important! perm is a bitmask!
{
    // debit code goes here
}

Q: How does this know what agent to get the permissions from?
A: The last person who requested permissions. Use llGetPermissionsKey to find out the key of the agent.

Q: Is there a way to find out what permissions are already granted for a different agent, or do I need to keep a list of my own?
A: If you wanted a script to get permissions from more than one person, you would have to keep a list of your own.

Q: It's returning a value that I check against the constants listed in the table above, and nothing happens. What's up with that?
A: Are you sure you're using bitwise operators in your IF statement? (For instance, & instead of ==?) The value returned by llGetPermissions is a bitfield, and will not equal any of the above constants if more than one have been granted and are returned.

Compare with llRequestPermissions and llGetPermissionsKey.
