Use \fIcurl_easy_unescape(3)\fP instead! This function will convert the given URL encoded input string to a "plain string" and return that as a new allocated string. All input characters that are URL encoded (%XX where XX is a two-digit hexadecimal number) will be converted to their plain text versions. If the 'length' argument is set to 0, curl_unescape() will use strlen() on the input 'url' string to find out the size. You must \fIcurl_free(3)\fP the returned string when you're done with it. .SH AVAILABILITY Since 7.15.4, \fIcurl_easy_unescape(3)\fP should be used. This function will be removed in a future release. .SH RETURN VALUE A pointer to a null-terminated string or NULL if it failed. .SH "SEE ALSO" .br curl_easy_escape "(3)," curl_easy_unescape "(3)," curl_free "(3)," RFC 2396
