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. + +\fBCURLOPT_CONV_TO_NETWORK_FUNCTION\fP converts from host encoding to the +network encoding. It is used when commands or ASCII data are sent over the +network. + +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 DEFAULT +NULL +.SH PROTOCOLS +FTP, SMTP, IMAP, POP3 +.SH EXAMPLE +.nf +static CURLcode my_conv_from_ebcdic_to_ascii(char *buffer, size_t length) +{ + char *tempptrin, *tempptrout; + size_t bytes = length; + int rc; + tempptrin = tempptrout = buffer; + rc = platform_e2a(&tempptrin, &bytes, &tempptrout, &bytes); + if(rc == PLATFORM_CONV_OK) { + return CURLE_OK; + } + else { + return CURLE_CONV_FAILED; + } +} + +curl_easy_setopt(curl, CURLOPT_CONV_TO_NETWORK_FUNCTION, + my_conv_from_ebcdic_to_ascii); +.fi +.SH AVAILABILITY +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. +.SH "SEE ALSO" +.BR CURLOPT_CONV_FROM_NETWORK_FUNCTION "(3), " CURLOPT_CONV_FROM_UTF8_FUNCTION "(3), " |
