NAME

6       curl_unescape - URL decodes the given string
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       char *curl_unescape( const char *url, int length);
12

DESCRIPTION

14       Obsolete function. Use curl_easy_unescape(3) instead!
15
16       This  function  will  convert  the  given URL encoded input string to a
17       "plain string" and return that as a new  allocated  string.  All  input
18       characters  that are URL encoded (%XX where XX is a two-digit hexadeci‐
19       mal number) will be converted to their plain text versions.
20
21       If the 'length' argument is set to 0, curl_unescape() will use strlen()
22       on the input 'url' string to find out the size.
23
24       You must curl_free(3) the returned string when you are done with it.
25

EXAMPLE

27       CURL *curl = curl_easy_init();
28       if(curl) {
29         int decodelen;
30         char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen);
31         if(decoded) {
32           /* do not assume printf() works on the decoded data! */
33           printf("Decoded: ");
34           /* ... */
35           curl_free(decoded);
36         }
37       }
