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 converts 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) are converted to their plain text versions.

       If  the  length argument is set to 0, curl_unescape(3) calls strlen() on input to find out
       the size.

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

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           char *decoded = curl_unescape("%63%75%72%6c", 12);
           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 might be  removed  in  a
       future release.

RETURN VALUE

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