curl_unescape(3)		libcurl Manual		      curl_unescape(3)

       curl_unescape - URL decodes the given string

       #include <curl/curl.h>

       char *curl_unescape( char *url, int length );

       Obsolete function. Use curl_easy_unescape(3) 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 hexadeci‚Äź
       mal 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 curl_free() the returned string when you're done with it.

       Since  7.15.4, curl_easy_unescape(3) should be used. This function will
       be removed in a future release.

       A pointer to a zero terminated string or NULL if it failed.
