[SDK-DOC] Callbacks for Self-Installing Plug-ins :-)

[Guy Rabiller <guy(at)alamaison.fr>]

regarding the Execute ( Graphic Sequencer )

void <xgs_plugin-item_name>_Execute( const CRef& in_context, LPVOID 
*in_pUserData )

n_context



CRef <javascript:cpp_CRef.Click()> &



A reference to a GraphicSequencerContext 
<javascript:cpp_GraphicSequencerContext.Click()> object.

Wrong.

XSI crashes if you try to get a reference of the context. It should be:

void <xgs_plugin-item_name>_Execute( const CRef in_context, LPVOID 
*in_pUserData )

and actualy the DX9Display exemple uses the value, not the reference.

I got caught today by this one myself in one of our plugins. It's not an 
easy one to find, especialy because every other XSI plugin's callbacks 
use a reference on the context, it's weird that only this one ( and the 
_Init and _Term ) must use a value. Easy to fall in the trap. Is this by 
design ?
