\fBRSAENH_CPGetKeyParam\fR (RSAENH.@)
.SH SYNOPSIS
BOOL RSAENH_CPGetKeyParam
 (
  HCRYPTPROV \fIhProv\fR,
  HCRYPTKEY  \fIhKey\fR,
  DWORD      \fIdwParam\fR,
  BYTE*      \fIpbData\fR,
  DWORD*     \fIpdwDataLen\fR,
  DWORD      \fIdwFlags\fR
 )

.SH DESCRIPTION
.PP
Query a key parameter. 

.SH PARAMS
\fIhProv\fR \fB[In]\fR  The key container, which the key belongs to.
.PP
hHash \fB[In]\fR  The key object that is to be queried.
.PP
\fIdwParam\fR \fB[In]\fR  Specifies the parameter that is to be queried.
.PP
\fIpbData\fR \fB[In]\fR  Pointer to the buffer where the parameter value will be stored.
.PP
\fIpdwDataLen\fR \fB[In/Out]\fR  I: Buffer length at \fIpbData\fR, O: Length of the parameter value.
.PP
\fIdwFlags\fR \fB[In]\fR  None currently defined.
.PP

.SH RETURNS
.PP
\fBSuccess:\fR \fBTRUE\fR 
.PP
\fBFailure:\fR \fBFALSE\fR.
