curl_escape - URL encodes the given string
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>#include</B> <B><curl/curl.h></B>
<B>char</B> <B>*curl_escape(</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 input string to an
URL encoded string and return that as a new allocated
string. All input characters that are not a-z, A-Z or 0-9
will be converted to their "URL escaped" version (%NN
where NN is a two-digit hexadecimal number).
If the 'length' argument is set to 0, curl_escape() 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.

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