|
|
<p class="level0">Pass a pointer to your callback function, which should match the prototype shown above.
|
|
<p class="level0">Applies to non-ASCII platforms. <span Class="emphasis">curl_version_info(3)</span> will return the CURL_VERSION_CONV feature bit set if this option is provided.
|
|
<p class="level0">The data to be converted is in a buffer pointed to by the <span Class="emphasis">ptr</span> parameter. The amount of data to convert is indicated by the <span Class="emphasis">length</span> parameter. The converted data overlays the input data in the buffer pointed to by the ptr parameter. <span Class="emphasis">CURLE_OK</span> must be returned upon successful conversion. A CURLcode return value defined by curl.h, such as <span Class="emphasis">CURLE_CONV_FAILED</span>, should be returned if an error was encountered.
|
|
<p class="level0"><span Class="bold">CURLOPT_CONV_FROM_UTF8_FUNCTION</span> converts to host encoding from UTF8 encoding. It is required only for SSL processing.
|
|
<p class="level0">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.
|
|
<p class="level0">If HAVE_ICONV is defined, CURL_ICONV_CODESET_OF_HOST must also be defined. For example:
|
|
<p class="level0"> #define CURL_ICONV_CODESET_OF_HOST "IBM-1047"
|
|
<p class="level0">The iconv code in libcurl will default the network and UTF8 codeset names as follows:
|
|
<p class="level0"> #define CURL_ICONV_CODESET_OF_NETWORK "ISO8859-1"
|
|
<p class="level0"> #define CURL_ICONV_CODESET_FOR_UTF8 "UTF-8"
|
|
<p class="level0">You will need to override these definitions if they are different on your system. <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
