Syntax

STDAPI_(JsErrorCode) JsRunSerializedScriptWithCallback(  
  _In_ JsSerializedScriptLoadSourceCallback scriptLoadCallback,  
  _In_ JsSerializedScriptUnloadCallback scriptUnloadCallback,  
  _In_ BYTE *buffer,

  _Out_opt_ JsValueRef *result  
);  
  

Parameters

scriptLoadCallback
Callback called when the source code of the script needs to be loaded.

scriptUnloadCallback
Callback called when the serialized script and source code are no longer needed.

buffer
The serialized script.

sourceContext
A cookie identifying the script that can be used by debuggable script contexts. This context will passed into scriptLoadCallback and scriptUnloadCallback.

The code JsNoError if the operation succeeded, a failure code otherwise.

Remarks

Note

This API is not yet available for Store apps.

Requires an active script context.

The runtime will hold on to the buffer until all instances of any functions created from the buffer are garbage collected. It will then call scriptUnloadCallback to inform the caller that it is safe to release.
