=head1 NAME
CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values - CMS signed receipt request functions
=head1 SYNOPSIS
#include <openssl/cms.h>
CMS_ReceiptRequest *CMS_ReceiptRequest_create0(unsigned char *id, int idlen,
int allorfirst,
STACK_OF(GENERAL_NAMES) *receiptList,
STACK_OF(GENERAL_NAMES) *receiptsTo);
int CMS_add1_ReceiptRequest(CMS_SignerInfo *si, CMS_ReceiptRequest *rr);
int CMS_get1_ReceiptRequest(CMS_SignerInfo *si, CMS_ReceiptRequest **prr);
void CMS_ReceiptRequest_get0_values(CMS_ReceiptRequest *rr, ASN1_STRING **pcid,
int *pallorfirst,
STACK_OF(GENERAL_NAMES) **plist,
STACK_OF(GENERAL_NAMES) **prto);
=head1 DESCRIPTION
CMS_ReceiptRequest_create0() creates a signed receipt request structure. The
B<signedContentIdentifier> field is set using B<id> and B<idlen>, or it is set
to 32 bytes of pseudo random data if B<id> is NULL. If B<receiptList> is NULL
the allOrFirstTier option in B<receiptsFrom> is used and set to the value of
the B<allorfirst> parameter. If B<receiptList> is not NULL the B<receiptList>
option in B<receiptsFrom> is used. The B<receiptsTo> parameter specifies the
B<receiptsTo> field value.
The CMS_add1_ReceiptRequest() function adds a signed receipt request B<rr>
to SignerInfo structure B<si>.
int CMS_get1_ReceiptRequest() looks for a signed receipt request in B<si>, if
any is found it is decoded and written to B<prr>.
CMS_ReceiptRequest_get0_values() retrieves the values of a receipt request.
The signedContentIdentifier is copied to B<pcid>. If the B<allOrFirstTier>
option of B<receiptsFrom> is used its value is copied to B<pallorfirst>
otherwise the B<receiptList> field is copied to B<plist>. The B<receiptsTo>
parameter is copied to B<prto>.
=head1 NOTES
For more details of the meaning of the fields see RFC2634.
The contents of a signed receipt should only be considered meaningful if the
corresponding CMS_ContentInfo structure can be successfully verified using
CMS_verify().
=head1 RETURN VALUES
CMS_ReceiptRequest_create0() returns a signed receipt request structure or
NULL if an error occurred.
CMS_add1_ReceiptRequest() returns 1 for success or 0 if an error occurred.
CMS_get1_ReceiptRequest() 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.
