Data pointer to pass to the ssl context callback set by the option
\fICURLOPT_SSL_CTX_FUNCTION\fP, this is the pointer you'll get as third
parameter, otherwise \fBNULL\fP. (Added in 7.11.0)
.IP CURLOPT_CONV_TO_NETWORK_FUNCTION
.IP CURLOPT_CONV_FROM_NETWORK_FUNCTION
.IP CURLOPT_CONV_FROM_UTF8_FUNCTION
Function pointers that should match the following prototype: CURLcode
function(char *ptr, size_t length);
These three options apply to non-ASCII platforms only. They are available
only if \fBCURL_DOES_CONVERSIONS\fP was defined when libcurl was built. When
this is the case, \fIcurl_version_info(3)\fP will return the CURL_VERSION_CONV
feature bit set.
The data to be converted is in a buffer pointed to by the ptr parameter. The
amount of data to convert is indicated by the length parameter. The converted
data overlays the input data in the buffer pointed to by the ptr parameter.
CURLE_OK should be returned upon successful conversion. A CURLcode return
value defined by curl.h, such as CURLE_CONV_FAILED, should be returned if an
error was encountered.
\fBCURLOPT_CONV_TO_NETWORK_FUNCTION\fP and
\fBCURLOPT_CONV_FROM_NETWORK_FUNCTION\fP convert between the host encoding and
the network encoding. They are used when commands or ASCII data are
sent/received over the network.
\fBCURLOPT_CONV_FROM_UTF8_FUNCTION\fP is called to convert from UTF8 into the
host encoding. It is required only for SSL processing.
If you set a callback pointer to NULL, or don't set it at all, the built-in
libcurl iconv functions will be used. If HAVE_ICONV was not defined when
libcurl was built, and no callback has been established, conversion will
return the CURLE_CONV_REQD error code.
If HAVE_ICONV is defined, CURL_ICONV_CODESET_OF_HOST must also be defined.
For example:
\&#define CURL_ICONV_CODESET_OF_HOST "IBM-1047"
The iconv code in libcurl will default the network and UTF8 codeset names as
follows:
\&#define CURL_ICONV_CODESET_OF_NETWORK "ISO8859-1"
\&#define CURL_ICONV_CODESET_FOR_UTF8 "UTF-8"
You will need to override these definitions if they are different on your
system.

.SH NAME
curl_version_info - returns run-time libcurl version info
.SH SYNOPSIS
@ -98,6 +119,9 @@ libcurl was built with support for SSPI. This is only available on Windows and
makes libcurl use Windows-provided functions for NTLM authentication. It also
allows libcurl to use the current user and the current user's password without
the app having to pass them on. (Added in 7.13.2)
.IP CURL_VERSION_CONV
libcurl was built with support for character conversions, as provided by the
CUURLOPT_CONV_* callbacks. (Added in 7.15.4)
.RE
\fIssl_version\fP is an ascii string for the OpenSSL version used. If libcurl
has no SSL support, this is NULL.
