NAME
       curl_unescape - URL decodes the given string

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Obsolete function. Use _easy_unescape&section=3">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 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 _free&section=3">curl_free(3) the returned string when you're done with it.

AVAILABILITY
       Since 7.15.4, _easy_unescape&section=3">curl_easy_unescape(3) should be used. This function will
       be removed in a future release.

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