curl_easy_unescape(3)		libcurl Manual		 curl_easy_unescape(3)

       curl_easy_unescape - URL decodes the given string

       #include <curl/curl.h>

       char  *curl_easy_unescape(  CURL	 *curl,	 char *url, int inlength , int
       *outlength );

       This function converts the given URL encoded input string to  a	"plain
       string" and returns that in an allocated memory area. All input charac‐
       ters that are URL encoded (%XX where XX is a two-digit hexadecimal num‐
       ber) are converted to their binary versions.

       If  the	length argument is set to 0 (zero), curl_easy_unescape(3) will
       use strlen() on the input url string to find out the size.

       If outlength is non-NULL, the function will write  the  length  of  the
       returned	 string	 in  the  integer it points to. This allows an escaped
       string containing %00 to still get used properly after unescaping.

       You must curl_free(3) the returned string when you're done with it.

       Added in 7.15.4 and replaces the old curl_unescape(3) function.

       A pointer to a zero terminated string or NULL if it failed.
