IResourceHandlerRead Method

Version 92.0.260
Read response data. If data is available immediately copy up to dataOut.Length bytes into dataOut, set bytesRead to the number of bytes copied, and return true. To read the data at a later time keep a pointer to dataOut, set bytesRead to 0, return true and execute callback when the data is available (dataOut will remain valid until the callback is executed). To indicate response completion set bytesRead to 0 and return false. To indicate failure set bytesRead to < 0 (e.g. -2 for ERR_FAILED) and return false. This method will be called in sequence but not from a dedicated thread. For backwards compatibility set bytesRead to -1 and return false and the ReadResponse method will be called.
