Expand description

@function @abstract Creates a JavaScript Typed Array object from an existing JavaScript Array Buffer object with the given offset and length. @param ctx The execution context to use. @param arrayType A value identifying the type of array to create. If arrayType is kJSTypedArrayTypeNone or kJSTypedArrayTypeArrayBuffer then NULL will be returned. @param buffer An Array Buffer object that should be used as the backing store for the created JavaScript Typed Array object. @param byteOffset The byte offset for the created Typed Array. byteOffset should aligned with the element size of arrayType. @param length The number of elements to include in the Typed Array. @param exception A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception. @result A JSObjectRef that is a Typed Array or NULL if there was an error. The backing store of the Typed Array will be buffer.
