NAME

       curl_escape - URL encode a string

SYNOPSIS

       #include <curl/curl.h>

       char *curl_escape(const char *string, int length);

DESCRIPTION

       Obsolete function. Use curl_easy_escape(3) instead.

       This  function converts the given input string to a URL encoded string and return that as a new allocated
       string. All input characters that are not a-z, A-Z or 0-9 are 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(3) uses strlen() on string to find out the size.

       You must curl_free(3) the returned string when you are done with it.

           curl_free(output);
         }
