curl_unescape - URL decodes the given string

SYNOPSIS

       #include <curl/curl.h>
       char *curl_unescape( const char *url, int length);

DESCRIPTION

       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  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 curl_free(3) the returned string when you are done with it.

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         int decodelen;
         char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen);
         if(decoded) {
           /* do not assume printf() works on the decoded data! */
           printf("Decoded: ");
           /* ... */
           curl_free(decoded);

AVAILABILITY

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

RETURN VALUE

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