25: .SH NAME
26: curl_easy_escape - URL encodes the given string
27: .SH SYNOPSIS
28: .B #include <curl/curl.h>
29: .sp
30: .BI "char *curl_easy_escape( CURL *" curl ", const char *" string
31: .BI ", int "length " );"
32: .ad
33: .SH DESCRIPTION
34: This function converts the given input \fIstring\fP to a URL encoded string
35: and returns that as a new allocated string. All input characters that are not
36: a-z, A-Z, 0-9, '-', '.', '_' or '~' are converted to their "URL escaped"
37: version (%NN where NN is a two-digit hexadecimal number).
38:
39: If \fIlength\fP is set to 0 (zero), \fIcurl_easy_escape(3)\fP uses strlen() on
40: the input \fIstring\fP to find out the size.
41:
42: You must \fIcurl_free(3)\fP the returned string when you're done with it.
43: .SH ENCODING
44: libcurl is typically not aware of, nor does it care about, character
45: encodings. \fIcurl_easy_escape(3)\fP encodes the data byte-by-byte into the
46: URL encoded version without knowledge or care for what particular character
47: encoding the application or the receiving server may assume that the data
48: uses.
49:
50: The caller of \fIcurl_easy_escape(3)\fP must make sure that the data passed in
51: to the function is encoded correctly.
52: .SH AVAILABILITY
53: Added in 7.15.4 and replaces the old \fIcurl_escape(3)\fP function.
54: .SH RETURN VALUE
55: A pointer to a zero terminated string or NULL if it failed.
56: .SH EXAMPLE
57: .nf
58: CURL *curl = curl_easy_init();
59: if(curl) {
60: char *output = curl_easy_escape(curl, "data to convert", 15);
61: if(output) {
62: printf("Encoded: %s\\n", output);
63: curl_free(output);
