NAME

       curl_easy_unescape - URL decodes the given string

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       This  function  converts  the  given  URL encoded input string to a "plain string" and returns that in an
       allocated memory area. All input characters that are URL encoded (%XX where XX is a two-digit hexadecimal
       number) 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.
       Since this is a pointer to an int type, it can only return a value up to INT_MAX so no longer string  can
       be unescaped if the string length is returned in this parameter.

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

AVAILABILITY

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

RETURN VALUE

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