Clarify that the '-', '.', '_' or '~' letters are also not escaped since
they shouldn't according to RFC3986 section 2.3.
This is how this function has behaved since sep 2010, commit
5df13c3173.

.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 " );"

.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.
