Use \fIcurl_easy_escape(3)\fP 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. .SH AVAILABILITY Since 7.15.4, \fIcurl_easy_escape(3)\fP should be used. This function will be removed in a future release. .SH RETURN VALUE A pointer to a zero terminated string or NULL if it failed. .SH "SEE ALSO" .BR curl_unescape "(3), " curl_free "(3), " RFC 2396
