  3. CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values - CMS signed receipt request functions
  4. =head1 SYNOPSIS
  5. #include <openssl/cms.h>
  6. CMS_ReceiptRequest *CMS_ReceiptRequest_create0(unsigned char *id, int idlen,
  7. int allorfirst,
  8. STACK_OF(GENERAL_NAMES) *receiptList,
  9. STACK_OF(GENERAL_NAMES) *receiptsTo);
  10. int CMS_add1_ReceiptRequest(CMS_SignerInfo *si, CMS_ReceiptRequest *rr);
  11. int CMS_get1_ReceiptRequest(CMS_SignerInfo *si, CMS_ReceiptRequest **prr);
  12. void CMS_ReceiptRequest_get0_values(CMS_ReceiptRequest *rr, ASN1_STRING **pcid,
  13. int *pallorfirst,
  14. STACK_OF(GENERAL_NAMES) **plist,
  15. STACK_OF(GENERAL_NAMES) **prto);
  16. =head1 DESCRIPTION
  17. CMS_ReceiptRequest_create0() creates a signed receipt request structure. The
  18. B<signedContentIdentifier> field is set using B<id> and B<idlen>, or it is set
  19. to 32 bytes of pseudo random data if B<id> is NULL. If B<receiptList> is NULL
  20. the allOrFirstTier option in B<receiptsFrom> is used and set to the value of
  21. the B<allorfirst> parameter. If B<receiptList> is not NULL the B<receiptList>
  22. option in B<receiptsFrom> is used. The B<receiptsTo> parameter specifies the
  23. B<receiptsTo> field value.
  24. The CMS_add1_ReceiptRequest() function adds a signed receipt request B<rr>
  25. to SignerInfo structure B<si>.
  26. int CMS_get1_ReceiptRequest() looks for a signed receipt request in B<si>, if
  27. any is found it is decoded and written to B<prr>.
  28. CMS_ReceiptRequest_get0_values() retrieves the values of a receipt request.
  29. The signedContentIdentifier is copied to B<pcid>. If the B<allOrFirstTier>
  30. option of B<receiptsFrom> is used its value is copied to B<pallorfirst>
  31. otherwise the B<receiptList> field is copied to B<plist>. The B<receiptsTo>
  32. parameter is copied to B<prto>.
  33. =head1 NOTES
  34. For more details of the meaning of the fields see RFC2634.
  35. The contents of a signed receipt should only be considered meaningful if the
  36. corresponding CMS_ContentInfo structure can be successfully verified using
  37. CMS_verify().
  38. =head1 RETURN VALUES
  39. CMS_ReceiptRequest_create0() returns a signed receipt request structure or
  40. NULL if an error occurred.
  41. CMS_add1_ReceiptRequest() returns 1 for success or 0 if an error occurred.
  42. CMS_get1_ReceiptRequest() returns 1 is a signed receipt request is found and
  43. decoded. It returns 0 if a signed receipt request is not present and -1 if
  44. it is present but malformed.
