If \fBmaxline\fR is zero a default value of 4k is used. The \s-1OCSP\s0 request \fBreq\fR may be set to \fB\s-1NULL\s0\fR and provided later if required. .PP \&\fBOCSP_sendreq_nbio()\fR performs nonblocking I/O on the \s-1OCSP\s0 request context \&\fBrctx\fR. When the operation is complete it returns the response in \fB*presp\fR. .PP \&\fBOCSP_REQ_CTX_free()\fR frees up the \s-1OCSP\s0 context \fBrctx\fR. .PP \&\fBOCSP_set_max_response_length()\fR sets the maximum response length for \fBrctx\fR to \fBlen\fR. If the response exceeds this length an error occurs. If not set a default value of 100k is used. .PP \&\fBOCSP_REQ_CTX_add1_header()\fR adds header \fBname\fR with value \fBvalue\fR to the context \fBrctx\fR. It can be called more than once to add multiple headers. It \fB\s-1MUST\s0\fR be called before any calls to \fBOCSP_sendreq_nbio()\fR. The \fBreq\fR parameter in the initial to \fBOCSP_sendreq_new()\fR call \s-1MUST\s0 be set to \fB\s-1NULL\s0\fR if additional headers are set. .PP \&\fBOCSP_REQ_CTX_set1_req()\fR sets the \s-1OCSP\s0 request in \fBrctx\fR to \fBreq\fR. This function should be called after any calls to \fBOCSP_REQ_CTX_add1_header()\fR. OCSP_REQ_CTX_set1_req(rctx, req) is equivalent to the following: .PP .Vb 2 \& OCSP_REQ_CTX_i2d(rctx, "application/ocsp\-request", \& ASN1_ITEM_rptr(OCSP_REQUEST), (ASN1_VALUE *)req) .Ve .PP \&\fBOCSP_REQ_CTX_i2d()\fR sets the request context \fBrctx\fR to have the request \&\fBreq\fR, which has the \s-1ASN.1\s0 type \fBit\fR. The \fBcontent_type\fR, if not \s-1NULL,\s0 will be included in the \s-1HTTP\s0 request. The function should be called after all other headers have already been added. .PP \&\fBOCSP_sendreq_bio()\fR performs an \s-1OCSP\s0 request using the responder \fBio\fR, the \s-1URL\s0 path \fBpath\fR, and the \s-1OCSP\s0 request \fBreq\fR with a response header maximum line length 4k. It waits indefinitely on a response. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBOCSP_sendreq_new()\fR returns a valid \fB\s-1OCSP_REQ_CTX\s0\fR structure or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBOCSP_sendreq_nbio()\fR returns \fB1\fR if the operation was completed successfully, \&\fB\-1\fR if the operation should be retried and \fB0\fR if an error occurred. .PP \&\fBOCSP_REQ_CTX_add1_header()\fR, \fBOCSP_REQ_CTX_set1_req()\fR, and \fBOCSP_REQ_CTX_i2d()\fR return \fB1\fR for success and \fB0\fR for failure. .PP \&\fBOCSP_sendreq_bio()\fR returns the \fB\s-1OCSP_RESPONSE\s0\fR structure sent by the responder or \fB\s-1NULL\s0\fR if an error occurred. .PP \&\fBOCSP_REQ_CTX_free()\fR and \fBOCSP_set_max_response_length()\fR do not return values. .SH "NOTES" .IX Header "NOTES" These functions only perform a minimal \s-1HTTP\s0 query to a responder. If an application wishes to support more advanced features it should use an alternative more complete \s-1HTTP\s0 library. .PP Currently only \s-1HTTP POST\s0 queries to responders are supported. .PP The arguments to \fBOCSP_sendreq_new()\fR correspond to the components of the \s-1URL.\s0 For example if the responder \s-1URL\s0 is \fBhttp://ocsp.com/ocspreq\fR the \s-1BIO\s0 \&\fBio\fR should be connected to host \fBocsp.com\fR on port 80 and \fBpath\fR should be set to \fB\*(L"/ocspreq\*(R"\fR .PP The headers added with \fBOCSP_REQ_CTX_add1_header()\fR are of the form "\fBname\fR: \fBvalue\fR\*(L" or just \*(R"\fBname\fR" if \fBvalue\fR is \fB\s-1NULL\s0\fR. So to add a Host header for \fBocsp.com\fR you would call: .PP .Vb 1 \& OCSP_REQ_CTX_add1_header(ctx, "Host", "ocsp.com"); .Ve .PP If \fBOCSP_sendreq_nbio()\fR indicates an operation should be retried the corresponding \s-1BIO\s0 can be examined to determine which operation (read or write) should be retried and appropriate action taken (for example a \fBselect()\fR call on the underlying socket). .PP \&\fBOCSP_sendreq_bio()\fR does not support retries and so cannot handle nonblocking I/O efficiently. It is retained for compatibility and its use in new applications is not recommended. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBcrypto\fR\|(7), \&\fBOCSP_cert_to_id\fR\|(3), \&\fBOCSP_request_add1_nonce\fR\|(3), \&\fBOCSP_REQUEST_new\fR\|(3), \&\fBOCSP_resp_find_status\fR\|(3), \&\fBOCSP_response_status\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2015\-2020 The OpenSSL Project Authors.
