=pod =head1 NAME CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values - CMS signed receipt request functions. =head1 SYNOPSIS #include 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 field is set using B and B, or it is set to 32 bytes of pseudo random data if B is NULL. If B is NULL the allOrFirstTier option in B is used and set to the value of the B parameter. If B is not NULL the B option in B is used. The B parameter specifies the B field value. The CMS_add1_ReceiptRequest() function adds a signed receipt request B to SignerInfo structure B. int CMS_get1_ReceiptRequest() looks for a signed receipt request in B, if any is found it is decoded and written to B. CMS_ReceiptRequest_get0_values() retrieves the values of a receipt request. The signedContentIdentifier is copied to B. If the B option of B is used its value is copied to B otherwise the B field is copied to B. The B parameter is copied to B. =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 is 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. =head1 SEE ALSO L, L, L, L L =cut =head1 COPYRIGHT Copyright 2008-2016 The OpenSSL Project Authors.
