Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "CMS_get1_ReceiptRequest 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
CMS_ReceiptRequest_create0_ex, CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values \- CMS signed receipt request functions Header "SYNOPSIS" .Vb 1 #include <openssl/cms.h> \& CMS_ReceiptRequest *CMS_ReceiptRequest_create0_ex( unsigned char *id, int idlen, int allorfirst, STACK_OF(GENERAL_NAMES) *receiptList, STACK_OF(GENERAL_NAMES) *receiptsTo, OSSL_LIB_CTX *libctx); 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); .Ve Header "DESCRIPTION" \fBCMS_ReceiptRequest_create0_ex() creates a signed receipt request structure. The signedContentIdentifier field is set using id and idlen, or it is set to 32 bytes of pseudo random data if id is NULL. If receiptList is NULL the allOrFirstTier option in receiptsFrom is used and set to the value of the allorfirst parameter. If receiptList is not NULL the receiptList option in receiptsFrom is used. The receiptsTo parameter specifies the receiptsTo field value. The library context libctx is used to find the public random generator.

\fBCMS_ReceiptRequest_create0() is similar to \fBCMS_ReceiptRequest_create0_ex() but uses default values of NULL for the library context libctx.

The CMS_add1_ReceiptRequest() function adds a signed receipt request rr to SignerInfo structure si.

int CMS_get1_ReceiptRequest() looks for a signed receipt request in si, if any is found it is decoded and written to prr.

\fBCMS_ReceiptRequest_get0_values() retrieves the values of a receipt request. The signedContentIdentifier is copied to pcid. If the allOrFirstTier option of receiptsFrom is used its value is copied to pallorfirst otherwise the receiptList field is copied to plist. The receiptsTo parameter is copied to prto.

Header "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 \fBCMS_verify().

Header "RETURN VALUES" \fBCMS_ReceiptRequest_create0_ex() and CMS_ReceiptRequest_create0() return a signed receipt request structure or NULL if an error occurred.

\fBCMS_add1_ReceiptRequest() returns 1 for success or 0 if an error occurred.

\fBCMS_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.
