+.TH CURLOPT_PREREQFUNCTION 3 "2 Aug 2021" "libcurl 7.80.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_PREREQFUNCTION \- user callback called when a connection has been
+established, but before a request has been made.
+.SH SYNOPSIS
+.nf
+#include <curl/curl.h>
+
+/* These are the return codes for the pre-request callback. */
+#define CURL_PREREQFUNC_OK 0
+#define CURL_PREREQFUNC_ABORT 1 /* fail the entire transfer */
+
+int prereq_callback(void *clientp,
+ char *conn_primary_ip,
+ char *conn_local_ip,
+ int conn_primary_port,
+ int conn_local_port);
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREREQFUNCTION, prereq_callback);
+.SH DESCRIPTION
+Pass a pointer to your callback function, which should match the prototype
+shown above.
+
+This function gets called by libcurl after a connection has been established
+or a connection has been reused (including any SSL handshaking), but before any
+request is actually made on the connection. For example, for HTTP, this
+callback is called once a connection has been established to the server, but
+before a GET/HEAD/POST/etc request has been sent.
+
+This function may be called multiple times if redirections are enabled and are
+being followed (see \fICURLOPT_FOLLOWLOCATION(3)\fP).
+
+This function is passed the following information:
+.IP conn_primary_ip
+A nul-terminated pointer to a C string containing the primary IP of the remote
+server established with this connection. For FTP, this is the IP for the control
+connection. IPv6 addresses are represented without surrounding brackets.
+.IP conn_local_ip
+A nul-terminated pointer to a C string containing the originating IP for this
+connection. IPv6 addresses are represented without surrounding brackets.
+.IP conn_primary_port
+The primary port number on the remote server established with this connection.
+For FTP, this is the port for the control connection. This can be a TCP or a
+UDP port number dependending on the protocol.
+.IP conn_local_port
+The originating port number for this connection. This can be a TCP or a UDP port
+number dependending on the protocol.
+.RE
+
+\fIclientp\fP is the pointer you set with \fICURLOPT_PREREQDATA(3)\fP.
+
+The callback function must return \fICURL_PREREQFUNC_OK\fP on success, or
+\fICURL_PREREQFUNC_ABORT\fP to cause the transfer to fail.
+
+.SH DEFAULT
+By default, this is NULL and unused.
+.SH PROTOCOLS
+ALL
+.SH EXAMPLE
+.nf
+static int prereq_callback(void *clientp,
+ char *conn_primary_ip,
+ char *conn_local_ip,
+ int conn_primary_port,
+ int conn_local_port)
+{
