## UnloadAddonLib

### Description

Unloads an add-on library previously loaded by Softimage, allowing add-on developers to compile an add-on library while in use in Softimage. The following add-on library types can be unloaded: compiled operators, compiled custom commands, run-time shaders, events.
These add-on libraries can also be unloaded from the Libraries dialog located in the main menu under File > Addon > Libraries... Once you have unloaded an add-on library, the Softimage object connected to the library (for example, operators, shaders, etc... ) is no longer affected by the add-on until the library is loaded back. You don't need to reload the add-on explicitly since Softimage automatically reloads it when required. For instance, a compiled operator library is reloaded when an evaluation is required.

### Scripting Syntax

    UnloadAddonLib( FileName );

### Parameters

Parameter | Type | Description
--- | --- | ---
FileName | String | The full path of the library to unload. Default Value: A file browser prompts the user for a file if no filename is provided.
