.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 ", char *" url ", int "length " );"
.ad
.SH DESCRIPTION
This function converts the given input string to an 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 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.
