JsHasException Function

Determines whether the runtime of the current context is in an exception state.

Syntax

STDAPI_(JsErrorCode) JsHasException(  
   _Out_ bool *hasException  
);

Parameters

hasException
Whether the runtime of the current context is in the exception state.

Return Value

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

Remarks

If a call into the runtime results in an exception (either as the result of running a script or due to something like a conversion failure), the runtime is placed into an "exception state." All calls into any context created by the runtime (except for the exception APIs) will fail with JsErrorInExceptionState until the exception is cleared.

If the runtime of the current context is in the exception state when a callback returns into the engine, the engine will automatically rethrow the exception.

Requires an active script context.
