.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBOCSP_REQUEST_new()\fR allocates and returns an empty \fB\s-1OCSP_REQUEST\s0\fR structure.
.PP
\&\fBOCSP_REQUEST_free()\fR frees up the request structure \fBreq\fR.
.PP
\&\fBOCSP_request_add0_id()\fR adds certificate \s-1ID\s0 \fBcid\fR to \fBreq\fR. It returns
the \fB\s-1OCSP_ONEREQ\s0\fR structure added so an application can add additional
extensions to the request. The \fBid\fR parameter \fB\s-1MUST NOT\s0\fR be freed up after
the operation.
.PP
\&\fBOCSP_request_sign()\fR signs \s-1OCSP\s0 request \fBreq\fR using certificate
\&\fBsigner\fR, private key \fBkey\fR, digest \fBdgst\fR and additional certificates
\&\fBcerts\fR. If the \fBflags\fR option \fB\s-1OCSP_NOCERTS\s0\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 \fB\s-1OCSP_ONEREQ\s0\fR
structures in \fBreq\fR.
.PP
\&\fBOCSP_request_onereq_get0()\fR returns an internal pointer to the \fB\s-1OCSP_ONEREQ\s0\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 \fB\s-1OCSP_REQUEST\s0\fR structure or \fB\s-1NULL\s0\fR if
an error occurred.
.PP
\&\fBOCSP_request_add0_id()\fR returns the \fB\s-1OCSP_ONEREQ\s0\fR structure containing \fBcid\fR
or \fB\s-1NULL\s0\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 \fB\s-1OCSP_ONEREQ\s0\fR
structures in \fBreq\fR.
.PP
\&\fBOCSP_request_onereq_get0()\fR returns a pointer to an \fB\s-1OCSP_ONEREQ\s0\fR structure
or \fB\s-1NULL\s0\fR if the index value is out or range.
.SH "NOTES"
.IX Header "NOTES"
An \s-1OCSP\s0 request structure contains one or more \fB\s-1OCSP_ONEREQ\s0\fR structures
corresponding to each certificate.
.PP
\&\fBOCSP_request_onereq_count()\fR and \fBOCSP_request_onereq_get0()\fR are mainly used by
\&\s-1OCSP\s0 responders.
.SH "EXAMPLES"
.IX Header "EXAMPLES"
Create an \fB\s-1OCSP_REQUEST\s0\fR structure for certificate \fBcert\fR with issuer
\&\fBissuer\fR:
