.PP
\fIdata\fR \fB[Out]\fR  Destination for the values contents, or \fBNULL\fR if not required.
.PP

\fBSuccess:\fR \fBERROR_SUCCESS\fR. *\fIcount\fR is updated with the number of bytes copied to \fIdata\fR. 
.PP
\fBFailure:\fR \fBERROR_INVALID_HANDLE\fR, if \fIhkey\fR is invalid. \fBERROR_INVALID_PARAMETER\fR, if any other parameter is invalid. \fBERROR_MORE_DATA\fR, if on input *\fIcount\fR is too small to hold the contents. 

.SH NOTES
