DESCRIPTION
The

allocated structures for EVD parameters that the Provider fills.
The
evd_param_mask parameter allows Consumers to specify which
parameters to query. The Provider returns values for
evd_param_mask requested parameters. The Provider can return values for any of the
other parameters.
RETURN VALUES

DAT_INVALID_HANDLE The
evd_handle parameter is invalid.

evd_param_mask parameter is invalid.
