ULONG |
The property value (operation data) is of type ULONG and specifies the number of bytes that the miniport driver needs to reserve for its own use at the end of each downloaded DLS data buffer. The client then allocates each download buffer to be large enough to contain the requested number of bytes after the end of the downloaded data.
Return Value
A KSPROPERTY_SYNTH_DLS_APPEND property request returns STATUS_SUCCESS to indicate that it has completed successfully. Otherwise, the request returns an appropriate error status code. The following table shows some of the possible error codes.
| Status Code | Meaning |
