NAME

6       curl_easy_unescape - URL decodes the given string
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       char  *curl_easy_unescape(  CURL  *curl,  char *url, int inlength , int
12       *outlength );
13

DESCRIPTION

15       This function converts the given URL encoded input string to  a  "plain
16       string" and returns that in an allocated memory area. All input charac‐
17       ters that are URL encoded (%XX where XX is a two-digit hexadecimal num‐
18       ber) are converted to their binary versions.
19
20       If  the  length  argument is set to 0 (zero), curl_easy_unescape() will
21       use strlen() on the input url string to find out the size.
22
23       If outlength is non-NULL, the function will write  the  length  of  the
24       returned  string  in  the  integer it points to. This allows an escaped
25       string containing %00 to still get used properly after unescaping.
26
27       You must curl_free(3) the returned string when you're done with it.
28
