.SH DESCRIPTION
.sp
.LP
The \fBsasl_listmech()\fR interface returns a string listing the SASL names of
all the mechanisms available to the specified user. This call is typically
given to the client through a capability command or initial server response.
Client applications need this list so that they know what mechanisms the server
supports.
.SH PARAMETERS
.sp
.ne 2
.mk
.na
\fB\fIconn\fR\fR
.ad
.RS 10n
.rt  
The SASL context for this connection user restricts the mechanism list to those
mechanisms available to the user. This parameter is optional.
.RE

.sp
.ne 2
.mk
.na
\fB\fIuser\fR\fR
.ad
.RS 10n
.rt  
Restricts security mechanisms to those available to that user. The value of
\fIuser\fR may be \fINULL\fR, and it is not used if called by the client
application.
.RE

.sp
.ne 2
.mk
.na
\fB\fIprefix\fR\fR
.ad
.RS 10n
.rt  
Appended to the beginning of \fIresult\fR.
.RE

.sp
.ne 2
.mk
.na
\fB\fIsep\fR\fR
.ad
.RS 10n
.rt  
Appended between mechanisms.
.RE

.sp
.ne 2
.mk
.na
\fB\fIsuffix\fR\fR
.ad
.RS 10n
.rt  
Appended to the end of \fIresult\fR.
.RE

.sp
.ne 2
.mk
.na
\fB\fIresult\fR\fR
.ad
.RS 10n
.rt  
A null-terminated result string. \fIresult\fR must be allocated or freed by the
library.
.RE

.sp
.ne 2
.mk
.na
\fB\fIplen\fR\fR
.ad
.RS 10n
.rt  
The length of the result filled in by the library. The value of \fIplen\fR may
be \fINULL\fR.
.RE

.sp
.ne 2
.mk
.na
\fB\fIpcount\fR\fR
.ad
.RS 10n
.rt  
The number of mechanisms available. The value of \fIpcount\fR is filled in by
the library. The value of \fIpcount\fR may be \fINULL\fR
.RE

.SH RETURN VALUES
