Expand description
@function @abstract Creates a JavaScript Array Buffer object from an existing pointer. @param ctx The execution context to use. @param bytes A pointer to the byte buffer to be used as the backing store of the Typed Array object. @param byteLength The number of bytes pointed to by the parameter bytes. @param bytesDeallocator The allocator to use to deallocate the external buffer when the Typed Array data object is deallocated. @param deallocatorContext A pointer to pass back to the deallocator. @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 Array Buffer whose backing store is the same as the one pointed to by bytes or NULL if there was an error. @discussion If an exception is thrown during this function the bytesDeallocator will always be called.
