\r
26 curl_easy_escape - URL encodes the given string
\r
28 .B #include <curl/curl.h>
\r
30 .BI "char *curl_easy_escape( CURL *" curl ", char *" url ", int "length " );"
\r
33 This function converts the given input string to an URL encoded string and
\r
34 returns that as a new allocated string. All input characters that are not a-z,
\r
35 A-Z or 0-9 are converted to their "URL escaped" version (%NN where NN is a
\r
36 two-digit hexadecimal number).
\r
38 If the \fBlength\fP argument is set to 0 (zero), \fIcurl_easy_escape(3)\fP
\r
39 uses strlen() on the input \fBurl\fP to find out the size.
\r
41 You must \fIcurl_free(3)\fP the returned string when you're done with it.
\r
43 Added in 7.15.4 and replaces the old \fIcurl_escape(3)\fP function.
\r
45 A pointer to a zero terminated string or NULL if it failed.
