.... Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.
If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.
Avoid warning from groff about undefined register 'F'.

Title "OCSP_SENDREQ_NEW 3"
way too many mistakes in technical documents.
The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining \s-1OPENSSL_API_COMPAT\s0 with a suitable version value, see openssl_user_macros\|(7):
.Vb 8 typedef OSSL_HTTP_REQ_CTX OCSP_REQ_CTX; int OCSP_sendreq_nbio(OCSP_RESPONSE **presp, OSSL_HTTP_REQ_CTX *rctx); int OCSP_REQ_CTX_i2d(OCSP_REQ_CT *rctx, const ASN1_ITEM *it, ASN1_VALUE *req); int OCSP_REQ_CTX_add1_header(OCSP_REQ_CT *rctx, const char *name, const char *value); void OCSP_REQ_CTX_free(OCSP_REQ_CTX *rctx); void OCSP_set_max_response_length(OCSP_REQ_CT *rctx, unsigned long len); int OCSP_REQ_CTX_set1_req(OCSP_REQ_CTX *rctx, const OCSP_REQUEST *req); .Ve
The function OCSP_sendreq_new() builds a complete \s-1OSSL_HTTP_REQ_CTX\s0 structure with the \s-1BIO\s0 io to be used for requests and response, the \s-1URL\s0 path path, optionally the \s-1OCSP\s0 request req, and a response header maximum line length of buf_size. If buf_size is zero a default value of 4KiB is used. The req may be set to \s-1NULL\s0 and provided later using OCSP_REQ_CTX_set1_req() or OSSL_HTTP_REQ_CTX_set1_req\|(3). The io and path arguments to OCSP_sendreq_new() correspond to the components of the \s-1URL.\s0 For example if the responder \s-1URL\s0 is \*(C`http://example.com/ocspreq\*(C' the \s-1BIO\s0 \fIio should haven been connected to host \*(C`example.com\*(C' on port 80 and path should be set to \*(C`/ocspreq\*(C'.
\fBOCSP_sendreq_nbio() attempts to send the request prepared in rctx and to gather the response via \s-1HTTP,\s0 using the \s-1BIO\s0 io and path that were given when calling OCSP_sendreq_new(). If the operation gets completed it assigns the response, a pointer to a \s-1OCSP_RESPONSE\s0 structure, in *presp. The function may need to be called again if its result is -1, which indicates \fBBIO_should_retry\|(3). In such a case it is advisable to sleep a little in between, using BIO_wait\|(3) on the read \s-1BIO\s0 to prevent a busy loop.
\fBOCSP_sendreq_bio() combines OCSP_sendreq_new() with as many calls of \fBOCSP_sendreq_nbio() as needed and then OCSP_REQ_CTX_free(), with a response header maximum line length 4k. It waits indefinitely on a response. It does not support setting a timeout or adding headers and is retained for compatibility; use OSSL_HTTP_transfer\|(3) instead.
OCSP_REQ_CTX_i2d(rctx, it, req) is equivalent to the following:
.Vb 1 OSSL_HTTP_REQ_CTX_set1_req(rctx, "application/ocsp-request", it, req) .Ve
OCSP_REQ_CTX_set1_req(rctx, req) is equivalent to the following:
.Vb 3 OSSL_HTTP_REQ_CTX_set1_req(rctx, "application/ocsp-request", ASN1_ITEM_rptr(OCSP_REQUEST), (const ASN1_VALUE *)req) .Ve
The deprecated type and the remaining deprecated functions have been superseded by the following equivalents: \fB\s-1OCSP_REQ_CTX\s0 by \s-1OSSL_HTTP_REQ_CTX\s0\|(3), \fBOCSP_REQ_CTX_add1_header() by OSSL_HTTP_REQ_CTX_add1_header\|(3), \fBOCSP_REQ_CTX_free() by OSSL_HTTP_REQ_CTX_free\|(3), and \fBOCSP_set_max_response_length() by \fBOSSL_HTTP_REQ_CTX_set_max_response_length\|(3).
\fBOCSP_sendreq_nbio() returns 1 for success, 0 on error, -1 if retry is needed.
\fBOCSP_sendreq_bio() returns the \s-1OCSP_RESPONSE\s0 structure sent by the responder or \s-1NULL\s0 if an error occurred.
