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 the \fBlength\fP argument is set to 0 (zero), \fIcurl_easy_escape(3)\fP uses strlen() on the input \fBurl\fP to find out the size. You must \fIcurl_free(3)\fP the returned string when you're done with it. .SH AVAILABILITY Added in 7.15.4 and replaces the old \fIcurl_escape(3)\fP function. .SH RETURN VALUE A pointer to a zero terminated string or NULL if it failed. .SH "SEE ALSO" .BR curl_easy_unescape "(3), " curl_free "(3), " RFC 2396
