.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBOCSP_REQUEST_new()\fR allocates and returns an empty \fBOCSP_REQUEST\fR structure.
.PP
\&\fBOCSP_REQUEST_free()\fR frees up the request structure \fBreq\fR.
.PP
\&\fBOCSP_request_add0_id()\fR adds certificate ID \fBcid\fR to \fBreq\fR. It returns
the \fBOCSP_ONEREQ\fR structure added so an application can add additional
extensions to the request. The \fBid\fR parameter \fBMUST NOT\fR be freed up after
the operation.
.PP
\&\fBOCSP_request_sign()\fR signs OCSP request \fBreq\fR using certificate
\&\fBsigner\fR, private key \fBkey\fR, digest \fBdgst\fR and additional certificates
\&\fBcerts\fR. If the \fBflags\fR option \fBOCSP_NOCERTS\fR is set then no certificates
will be included in the request.
.PP
\&\fBOCSP_request_add1_cert()\fR adds certificate \fBcert\fR to request \fBreq\fR. The
application is responsible for freeing up \fBcert\fR after use.
.PP
\&\fBOCSP_request_onereq_count()\fR returns the total number of \fBOCSP_ONEREQ\fR
structures in \fBreq\fR.
.PP
\&\fBOCSP_request_onereq_get0()\fR returns an internal pointer to the \fBOCSP_ONEREQ\fR
contained in \fBreq\fR of index \fBi\fR. The index value \fBi\fR runs from 0 to
OCSP_request_onereq_count(req) \- 1.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOCSP_REQUEST_new()\fR returns an empty \fBOCSP_REQUEST\fR structure or \fBNULL\fR if
an error occurred.
.PP
\&\fBOCSP_request_add0_id()\fR returns the \fBOCSP_ONEREQ\fR structure containing \fBcid\fR
or \fBNULL\fR if an error occurred.
.PP
\&\fBOCSP_request_sign()\fR and \fBOCSP_request_add1_cert()\fR return 1 for success and 0
for failure.
.PP
\&\fBOCSP_request_onereq_count()\fR returns the total number of \fBOCSP_ONEREQ\fR
structures in \fBreq\fR and \-1 on error.
.PP
\&\fBOCSP_request_onereq_get0()\fR returns a pointer to an \fBOCSP_ONEREQ\fR structure
or \fBNULL\fR if the index value is out or range.
.SH NOTES
.IX Header "NOTES"
An OCSP request structure contains one or more \fBOCSP_ONEREQ\fR structures
corresponding to each certificate.
.PP
\&\fBOCSP_request_onereq_count()\fR and \fBOCSP_request_onereq_get0()\fR are mainly used by
OCSP responders.
.SH EXAMPLES
.IX Header "EXAMPLES"
Create an \fBOCSP_REQUEST\fR structure for certificate \fBcert\fR with issuer
\&\fBissuer\fR:
.PP
.Vb 2
\& OCSP_REQUEST *req;
\& OCSP_ID *cid;
\&
\& req = OCSP_REQUEST_new();
\& if (req == NULL)
\&    /* error */
\& cid = OCSP_cert_to_id(EVP_sha1(), cert, issuer);
\& if (cid == NULL)
\&    /* error */
\&
\& if (OCSP_REQUEST_add0_id(req, cid) == NULL)
\&    /* error */
\&
\& /* Do something with req, e.g. query responder */
\&
\& OCSP_REQUEST_free(req);
