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.  If  a
       sequence  of %NN (where NN is a two-digit hexadecimal num­
       ber) is found in the string to encode, that 3-letter  com­
       bination  will be copied to the output unmodifed, assuming
       that it is an already encoded piece of data.

       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 free() the returned string when you're done  with
       it.


RETURN VALUE

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