man curl_unescape (Fonctions bibliothèques) - URL decodes the given string
NAME
curl_unescape - URL decodes the given string
SYNOPSIS
#include <curl/curl.h> char *curl_unescape( char *url, int length );
DESCRIPTION
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() the returned string when you're done with it.
RETURN VALUE
A pointer to a zero terminated string or NULL if it failed.
