.SH SYNOPSIS
.LP
.nf
\fBcc\fR [ \fIflag\fR ... ] \fIfile\fR ... \fB-lsasl\fR   [ \fIlibrary\fR ... ]
#include <sasl/sasl.h>

\fBint\fR \fBsasl_getopt_t\fR(\fBvoid *\fR\fIcontext\fR, \fBconst char *\fR\fIplugin_name\fR,

.SH DESCRIPTION
.sp
.LP
The \fBsasl_getopt_t()\fR function allows a SASL configuration to be
encapsulated in the caller's configuration system. Some implementations may use
default configuration file(s) if this function is omitted. Configuration items
are arbitrary strings and are plug-in specific.
.SH PARAMETERS
.sp
.ne 2
.na
\fB\fIcontext\fR\fR
.ad
.RS 15n
The option context from the callback record.
.RE

.sp
.ne 2
.na
\fB\fIplugin_name\fR\fR
.ad
.RS 15n
The name of the plug-in. If the value of \fIplugin_name\fR is \fINULL\fR, the
the plug-in is a general SASL option.
.RE

.sp
.ne 2
.na
\fB\fIoption\fR\fR
.ad
.RS 15n
The name of the option.
.RE

.sp
.ne 2
.na
\fB\fIresult\fR\fR
.ad
.RS 15n
The value of \fIresult\fR is set and persists until the next call to
\fBsasl_getopt_t()\fR in the same thread. The value of \fIresult\fR is
unchanged if \fIoption\fR is not found.
.RE

.sp
.ne 2
.na
\fB\fIlen\fR\fR
.ad
.RS 15n
The length of \fIresult\fR. The value of \fIresult\fR can be \fINULL\fR.
.RE

.SH RETURN VALUES
.sp
.LP
Like other SASL callback functions, \fBsasl_getopt_t()\fR returns an integer
that corresponds to a SASL error code. See <\fBsasl.h\fR> for a complete list
of SASL error codes.
.SH ERRORS
.sp
.ne 2
.na
\fB\fBSASL_OK\fR\fR
