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.
