.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBCMS_ReceiptRequest_create0_ex()\fR creates a signed receipt request
structure. The \fBsignedContentIdentifier\fR field is set using \fIid\fR and \fIidlen\fR,
or it is set to 32 bytes of pseudo random data if \fIid\fR is NULL.
If \fIreceiptList\fR is NULL the allOrFirstTier option in \fIreceiptsFrom\fR is used
and set to the value of the \fIallorfirst\fR parameter. If \fIreceiptList\fR is not
NULL the \fIreceiptList\fR option in \fIreceiptsFrom\fR is used. The \fIreceiptsTo\fR
parameter specifies the \fIreceiptsTo\fR field value. The library context \fIlibctx\fR
is used to find the public random generator.
.PP
\&\fBCMS_ReceiptRequest_create0()\fR is similar to
\&\fBCMS_ReceiptRequest_create0_ex()\fR but uses default values of NULL for the
library context \fIlibctx\fR.
.PP
The \fBCMS_add1_ReceiptRequest()\fR function adds a signed receipt request \fBrr\fR
to SignerInfo structure \fBsi\fR.
.PP
int \fBCMS_get1_ReceiptRequest()\fR looks for a signed receipt request in \fBsi\fR, if
any is found it is decoded and written to \fBprr\fR.
.PP
\&\fBCMS_ReceiptRequest_get0_values()\fR retrieves the values of a receipt request.
The signedContentIdentifier is copied to \fBpcid\fR. If the \fBallOrFirstTier\fR
option of \fBreceiptsFrom\fR is used its value is copied to \fBpallorfirst\fR
otherwise the \fBreceiptList\fR field is copied to \fBplist\fR. The \fBreceiptsTo\fR
parameter is copied to \fBprto\fR.
.SH NOTES
.IX Header "NOTES"
For more details of the meaning of the fields see RFC2634.
.PP
The contents of a signed receipt should only be considered meaningful if the
corresponding CMS_ContentInfo structure can be successfully verified using
\&\fBCMS_verify()\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBCMS_ReceiptRequest_create0_ex()\fR and \fBCMS_ReceiptRequest_create0()\fR return
a signed receipt request structure or NULL if an error occurred.
.PP
\&\fBCMS_add1_ReceiptRequest()\fR returns 1 for success or 0 if an error occurred.
.PP
\&\fBCMS_get1_ReceiptRequest()\fR returns 1 is a signed receipt request is found and
decoded. It returns 0 if a signed receipt request is not present and \-1 if
it is present but malformed.
