|
|
.SH NAME
|
|
CURLOPT_CONV_FROM_UTF8_FUNCTION \- convert data from UTF8 to host encoding
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode conv_callback(char *ptr, size_t length);
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONV_FROM_UTF8_FUNCTION,
|
|
conv_callback);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to your callback function, which should match the prototype
|
|
shown above.
|
|
|
|
Applies to non\-ASCII platforms. \fIcurl_version_info(3)\fP returns the
|
|
CURL_VERSION_CONV feature bit set if this option is provided.
|
|
|
|
The data to be converted is in a buffer pointed to by the \fIptr\fP parameter.
|
|
The amount of data to convert is indicated by the \fIlength\fP parameter. The
|
|
converted data overlays the input data in the buffer pointed to by the ptr
|
|
parameter. \fICURLE_OK\fP must be returned upon successful conversion. A
|
|
CURLcode return value defined by curl.h, such as \fICURLE_CONV_FAILED\fP,
|
|
should be returned if an error was encountered.
|
|
|
|
\fICURLOPT_CONV_FROM_UTF8_FUNCTION(3)\fP converts to host encoding from UTF8
|
|
encoding. It is required only for SSL processing.
|
|
|
|
If you set a callback pointer to NULL, or do not set it at all, the built\-in
|
|
libcurl iconv functions are used. If HAVE_ICONV was not defined when libcurl
|
|
was built, and no callback has been established, the conversion returns the
|
|
CURLE_CONV_REQD error code.
|
|
|
|
If HAVE_ICONV is defined, CURL_ICONV_CODESET_OF_HOST must also be defined.
|
|
For example:
|
|
.nf
|
|
#define CURL_ICONV_CODESET_OF_HOST "IBM-1047"
|
|
.fi
|
|
|
|
The iconv code in libcurl defaults the network and UTF8 codeset names as
|
|
follows:
|
|
.nf
|
|
#define CURL_ICONV_CODESET_OF_NETWORK "ISO8859-1"
|
|
|
|
#define CURL_ICONV_CODESET_FOR_UTF8 "UTF-8"
|
|
.fi
|
|
|
|
You need to override these definitions if they are different on your system.
|
|
.SH DEFAULT
|
|
NULL
|
|
.SH PROTOCOLS
|
|
TLS\-based protocols.
|
|
.SH EXAMPLE
|
|
.nf
|
|
static CURLcode my_conv_from_utf8_to_ebcdic(char *buffer, size_t length)
|
|
{
|
|
int rc = 0;
|
|
/* in-place convert 'buffer' from UTF-8 to EBCDIC */
|
|
if(rc == 0) {
|
|
/* success */
|
|
return CURLE_OK;
|
|
}
|
|
else {
|
|
return CURLE_CONV_FAILED;
|
|
}
|
|
}
|
|
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
curl_easy_setopt(curl, CURLOPT_CONV_FROM_UTF8_FUNCTION,
|
|
my_conv_from_utf8_to_ebcdic);

|
|
.SH AVAILABILITY
|
|
Not available and deprecated since 7.82.0.
|
|
|

Available only if \fBCURL_DOES_CONVERSIONS\fP was defined when libcurl was
|
|
built.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
