### PrtQuery Parameter - pcbOutData

pcbOutData (PULONG) - in/out Points to the length of the output buffer.

On entry, this is set to the length of the buffer passed in. On exit, it is updated with the length of data available.

If ERROR_MORE_DATA(234) or NERR_BufTooSmall(2123) is set, this field has the buffer size required to get all available information on exit.
