27=head1 DESCRIPTION
28
29OCSP_REQUEST_new() allocates and returns an empty B<OCSP_REQUEST> structure.
30
31OCSP_REQUEST_free() frees up the request structure B<req>.
32
33OCSP_request_add0_id() adds certificate ID B<cid> to B<req>. It returns
34the B<OCSP_ONEREQ> structure added so an application can add additional
35extensions to the request. The B<id> parameter B<MUST NOT> be freed up after
36the operation.
37
38OCSP_request_sign() signs OCSP request B<req> using certificate
39B<signer>, private key B<key>, digest B<dgst> and additional certificates
40B<certs>. If the B<flags> option B<OCSP_NOCERTS> is set then no certificates
41will be included in the request.
42
43OCSP_request_add1_cert() adds certificate B<cert> to request B<req>. The
44application is responsible for freeing up B<cert> after use.
45
46OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ>
47structures in B<req>.
48
49OCSP_request_onereq_get0() returns an internal pointer to the B<OCSP_ONEREQ>
50contained in B<req> of index B<i>. The index value B<i> runs from 0 to
51OCSP_request_onereq_count(req) - 1.
52
53=head1 RETURN VALUES
54
55OCSP_REQUEST_new() returns an empty B<OCSP_REQUEST> structure or B<NULL> if
56an error occurred.
57
58OCSP_request_add0_id() returns the B<OCSP_ONEREQ> structure containing B<cid>
59or B<NULL> if an error occurred.
60
61OCSP_request_sign() and OCSP_request_add1_cert() return 1 for success and 0
62for failure.
63
64OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ>
65structures in B<req>.
66
67OCSP_request_onereq_get0() returns a pointer to an B<OCSP_ONEREQ> structure
68or B<NULL> if the index value is out or range.
69
70=head1 NOTES
71
72An OCSP request structure contains one or more B<OCSP_ONEREQ> structures
73corresponding to each certificate.
74
75OCSP_request_onereq_count() and OCSP_request_onereq_get0() are mainly used by
76OCSP responders.
77
78=head1 EXAMPLES
79
80Create an B<OCSP_REQUEST> structure for certificate B<cert> with issuer
81B<issuer>:
82
83 OCSP_REQUEST *req;
84 OCSP_ID *cid;
85
86 req = OCSP_REQUEST_new();
87 if (req == NULL)
88    /* error */
89 cid = OCSP_cert_to_id(EVP_sha1(), cert, issuer);
90 if (cid == NULL)
91    /* error */
92
93 if (OCSP_REQUEST_add0_id(req, cid) == NULL)
94    /* error */
95
96 /* Do something with req, e.g. query responder */
97
98 OCSP_REQUEST_free(req);
