NAME

       curl_unescape - URL decodes the given string

SYNOPSIS

       #include <curl/curl.h>

       char *curl_unescape(const char *input, int length);

DESCRIPTION

       Obsolete function. Use curl_easy_unescape(3) instead!

       This  function  will  convert  the URL encoded string input 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(3) will use strlen() on input 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.
