       curl_unescape - URL decodes the given string


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <B>#include</B> <B>&lt;curl/curl.h&gt;</B>

       <B>char</B> <B>*curl_unescape(</B> <B>char</B> <B>*</B><I>url</I><B>,</B> <B>int</B> <I>length</I> <B>);</B>


</PRE>
<H2>DESCRIPTION</H2><PRE>
       This  function  will  convert  the given URL encoded input
       string to a "plain string" and return that as a new  allo-
       cated  string.  All  input characters that are URL encoded
       (%XX where XX is a two-digit  hexadecimal  number,  or  +)
       will  be converted to their plain text versions (up to a ?
       letter, no + letters to the right of a ?  letter  will  be
       converted).

       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.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       A pointer to a  zero  terminated  string  or  NULL  if  it
       failed.
