curl_escape - URL encodes the given string

SYNOPSIS

       #include <curl/curl.h>

       char *curl_escape( char *url, int length );

DESCRIPTION

       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.

RETURN VALUE

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