<p>CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values - CMS signed receipt request functions</p>
<h1 id="SYNOPSIS">SYNOPSIS</h1>
<pre><code> #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);

<h1 id="DESCRIPTION">DESCRIPTION</h1>
<p>CMS_ReceiptRequest_create0() creates a signed receipt request structure. The <b>signedContentIdentifier</b> field is set using <b>id</b> and <b>idlen</b>, or it is set to 32 bytes of pseudo random data if <b>id</b> is NULL. If <b>receiptList</b> is NULL the allOrFirstTier option in <b>receiptsFrom</b> is used and set to the value of the <b>allorfirst</b> parameter. If <b>receiptList</b> is not NULL the <b>receiptList</b> option in <b>receiptsFrom</b> is used. The <b>receiptsTo</b> parameter specifies the <b>receiptsTo</b> field value.</p>
<p>The CMS_add1_ReceiptRequest() function adds a signed receipt request <b>rr</b> to SignerInfo structure <b>si</b>.</p>
<p>int CMS_get1_ReceiptRequest() looks for a signed receipt request in <b>si</b>, if any is found it is decoded and written to <b>prr</b>.</p>
<p>CMS_ReceiptRequest_get0_values() retrieves the values of a receipt request. The signedContentIdentifier is copied to <b>pcid</b>. If the <b>allOrFirstTier</b> option of <b>receiptsFrom</b> is used its value is copied to <b>pallorfirst</b> otherwise the <b>receiptList</b> field is copied to <b>plist</b>. The <b>receiptsTo</b> parameter is copied to <b>prto</b>.</p>
<h1 id="NOTES">NOTES</h1>
<p>For more details of the meaning of the fields see RFC2634.</p>
<p>The contents of a signed receipt should only be considered meaningful if the corresponding CMS_ContentInfo structure can be successfully verified using CMS_verify().</p>
<h1 id="RETURN-VALUES">RETURN VALUES</h1>
<p>CMS_ReceiptRequest_create0() returns a signed receipt request structure or NULL if an error occurred.</p>
<p>CMS_add1_ReceiptRequest() returns 1 for success or 0 if an error occurred.</p>
<p>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.</p>
