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>.
32If the argument is NULL, nothing is done.
33
34OCSP_request_add0_id() adds certificate ID B<cid> to B<req>. It returns
35the B<OCSP_ONEREQ> structure added so an application can add additional
36extensions to the request. The B<id> parameter B<MUST NOT> be freed up after
37the operation.
38
39OCSP_request_sign() signs OCSP request B<req> using certificate
40B<signer>, private key B<key>, digest B<dgst> and additional certificates
41B<certs>. If the B<flags> option B<OCSP_NOCERTS> is set then no certificates
42will be included in the request.
43
44OCSP_request_add1_cert() adds certificate B<cert> to request B<req>. The
45application is responsible for freeing up B<cert> after use.
46
47OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ>
48structures in B<req>.
49
50OCSP_request_onereq_get0() returns an internal pointer to the B<OCSP_ONEREQ>
51contained in B<req> of index B<i>. The index value B<i> runs from 0 to
52OCSP_request_onereq_count(req) - 1.
53
54=head1 RETURN VALUES
55
56OCSP_REQUEST_new() returns an empty B<OCSP_REQUEST> structure or B<NULL> if
57an error occurred.
58
59OCSP_request_add0_id() returns the B<OCSP_ONEREQ> structure containing B<cid>
60or B<NULL> if an error occurred.
61
62OCSP_request_sign() and OCSP_request_add1_cert() return 1 for success and 0
63for failure.
64
65OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ>
66structures in B<req> and -1 on error.
67
68OCSP_request_onereq_get0() returns a pointer to an B<OCSP_ONEREQ> structure
69or B<NULL> if the index value is out or range.
70
71=head1 NOTES
72
73An OCSP request structure contains one or more B<OCSP_ONEREQ> structures
74corresponding to each certificate.
75
76OCSP_request_onereq_count() and OCSP_request_onereq_get0() are mainly used by
77OCSP responders.
78
79=head1 EXAMPLES
80
81Create an B<OCSP_REQUEST> structure for certificate B<cert> with issuer
82B<issuer>:
83
84 OCSP_REQUEST *req;
85 OCSP_ID *cid;
86
87 req = OCSP_REQUEST_new();
88 if (req == NULL)
89    /* error */
90 cid = OCSP_cert_to_id(EVP_sha1(), cert, issuer);
91 if (cid == NULL)
92    /* error */
93
94 if (OCSP_REQUEST_add0_id(req, cid) == NULL)
95    /* error */
96
97 /* Do something with req, e.g. query responder */
98
99 OCSP_REQUEST_free(req);
