22 .TH curl_escape 3 "February 03, 2016" "libcurl 7.59.0" "libcurl Manual"
25 curl_escape - URL encodes the given string
27 .B #include <curl/curl.h>
29 .BI "char *curl_escape( const char *" url ", int "length " );"
32 Obsolete function. Use \fIcurl_easy_escape(3)\fP instead!
34 This function will convert the given input string to an URL encoded string and
35 return that as a new allocated string. All input characters that are not a-z,
36 A-Z or 0-9 will be converted to their "URL escaped" version (%NN where NN is a
37 two-digit hexadecimal number).
39 If the 'length' argument is set to 0, curl_escape() will use strlen() on the
40 input 'url' string to find out the size.
42 You must curl_free() the returned string when you're done with it.
44 Since 7.15.4, \fIcurl_easy_escape(3)\fP should be used. This function will
45 be removed in a future release.
47 A pointer to a zero terminated string or NULL if it failed.
