+.TH curl_easy_escape 3 "7 April 2006" "libcurl 7.15.4" "libcurl Manual"
+.SH NAME
+curl_easy_escape - URL encodes the given string
+.SH SYNOPSIS
+.B #include <curl/curl.h>
+.sp
+.BI "char *curl_easy_escape( CURL *" curl ", const char *" string
+.BI ", int "length " );"
+.ad
+.SH DESCRIPTION
+This function converts the given input \fIstring\fP to a URL encoded string
+and returns that as a new allocated string. 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 \fIlength\fP is set to 0 (zero), \fIcurl_easy_escape(3)\fP uses strlen() on
+the input \fIstring\fP to find out the size.
+
+You must \fIcurl_free(3)\fP the returned string when you're done with it.
+.SH ENCODING
+libcurl is typically not aware of, nor does it care about, character
+encodings. \fIcurl_easy_escape(3)\fP encodes the data byte-by-byte into the
+URL encoded version without knowledge or care for what particular character
+encoding the application or the receiving server may assume that the data
+uses.
+
+The caller of \fIcurl_easy_escape(3)\fP must make sure that the data passed in
+to the function is encoded correctly.
+.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 EXAMPLE
+.nf
+CURL *curl = curl_easy_init();
+if(curl) {
+  char *output = curl_easy_escape(curl, "data to convert", 15);
+  if(output) {
+    printf("Encoded: %s\\n", output);
+    curl_free(output);
+  }
+}
