CentOS 7.0 - man page for curl_unescape (centos section 3)

curl_unescape(3)			  libcurl Manual			 curl_unescape(3)

NAME
       curl_unescape - URL decodes the given string

SYNOPSIS
       #include <curl/curl.h>

       char *curl_unescape( char *url, int length );

DESCRIPTION
       Obsolete function. Use curl_easy_unescape(3) instead!

       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 ver-
       sions.

       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.

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 zero terminated string or NULL if it failed.
