SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       obsolete function. use curl_easy_escape(3) instead!

       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.

AVAILABILITY
       since 7.15.4, curl_easy_escape(3) should be used. this function will be
       removed in a future release.

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