.SH DESCRIPTION
.sp
.LP
Use the \fBsasl_client_new()\fR interface to create a new SASL context. This
SASL context will be used for all SASL calls for one connection. The context
handles both authentication and the integrity and encryption layers after
authentication.
.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIservice\fR\fR
.ad
.RS 16n
The registered name of the service that uses SASL, usually the protocol name,
for example, IMAP.
.RE

.sp
.ne 2
.na
\fB\fIserverFQDN\fR\fR
.ad
.RS 16n
The fully qualified domain name of the server, for example, serverhost.cmu.edu.
.RE

.sp
.ne 2
.na
\fB\fIiplocalport\fR\fR
.ad
.RS 16n
.sp
.LP
The IP and port of the local side of the connection, or \fINULL\fR. If
\fIiplocalport\fR is \fINULL\fR, mechanisms that require IP address information
are disabled. The \fIiplocalport\fR string must be in one of the following
formats:

.RE

.sp
.ne 2
.na
\fB\fIprompt_supp\fR\fR
.ad
.RS 16n
A list of the client interactions supported that are unique to this connection.
If this parameter is \fINULL\fR, the global callbacks specified in
\fBsasl_client_init\fR(3SASL) are used.
.RE

.sp
.ne 2

Usage flags. For clients, the flag \fBSASL_NEED_PROXY\fR is available.
.RE

.sp
.ne 2
.na
\fB\fIpconn\fR\fR
.ad
.RS 16n
The connection context allocated by the library. The \fIpconn\fR structure is
used for all future SASL calls for this connection.
.RE

.SH RETURN VALUES
.sp
.LP
\fBsasl_client_new()\fR returns an integer that corresponds to a SASL error
code.
.SH ERRORS
.sp
.ne 2
.na
\fB\fBSASL_OK\fR\fR

All other error codes indicate an error situation that must be handled, or the
authentication session should be quit. See \fBsasl_errors\fR(3SASL) for
