NAME
       curl_easy_escape - URL encodes the given string

SYNOPSIS
       #include <curl/curl.h>

       char *curl_easy_escape( CURL *curl, const char *string , int length );

DESCRIPTION
       This  function  converts the given input string to a URL encoded string
       and returns that as a new allocated string. All input  characters  that
       are not a-z, A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL
       escaped" version (%NN where NN is a two-digit hexadecimal number).

       If length is set to 0 (zero), curl_easy_escape(3) uses strlen() on  the
       input string to find out the size.

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

ENCODING
       libcurl	is  typically  not aware of, nor does it care about, character
       encodings. curl_easy_escape(3) encodes the data byte-by-byte  into  the
       URL encoded version without knowledge or care for what particular char-
       acter encoding the application or the receiving server may assume  that
       the data uses.

       The  caller  of curl_easy_escape(3) must make sure that the data passed
       in to the function is encoded correctly.

AVAILABILITY
       Added in 7.15.4 and replaces the old curl_escape(3) function.

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

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
	 char *output = curl_easy_escape(curl, "data to convert", 15);
	 if(output) {
	   printf("Encoded: %s\n", output);
	   curl_free(output);
	 }
       }
