.B const char *option,
.TP

.B unsigned * len);
\fBsasl_getopt_t\fP is used to retrieve an option, often mechanism specific,
from the application. An example of this is
requesting what KERBEROS_V4 srvtab file to use.

.B Parameters
.INDENT 7.0
.IP \(bu 2
\fBcontext\fP – is the SASL connection context
.IP \(bu 2
\fBplugin_name\fP – is the plugin this value is for.
.IP \(bu 2
\fBoption\fP – is a string representing the option. A common option that all
server applications should handle is the method for checking
plaintext passwords.  See the \fI\%administrators
guide\fP for a
full description of this option.
.UNINDENT
.UNINDENT
.sp
Memory management of options supplied by the getopt callback
should be done by the application, however, any
requested option must remain available until the callback
is no longer valid.  That is, when sasl_dispose(3) is called
for a the connection it is associated with,  or  sasl_done(3)
is called for global callbacks.
.UNINDENT
.SH RETURN VALUE
.sp
SASL callback functions should return SASL return codes.
See sasl.h for a complete list. \fBSASL_OK\fP indicates success.
.sp
Other return codes indicate errors and should be handled.
