.SH NAME
t_sysconf \- get configurable XTI variables
.SH SYNOPSIS
.LP
.nf
#include <xti.h>
\fBint\fR \fBt_sysconf\fR(\fBint\fR\fIname\fR);
.fi
.SH DESCRIPTION
.sp
.LP
The \fBt_sysconf()\fR function provides a method for the application to
determine the current value of configurable and implementation-dependent XTI
limits or options.
.sp
.LP
The \fIname\fR argument represents the XTI system variable to be queried. The
following table lists the minimal set of XTI system variables from
\fB<xti.h>\fR that can be returned by \fBt_sysconf()\fR, and the symbolic
constants, defined in \fB<xti.h>\fR that are the corresponding values used for
\fIname\fR.

.SH RETURN VALUES
.sp
.LP
If \fIname\fR is valid, \fBt_sysconf()\fR returns the value of the requested
limit/option, which might be -1, and leaves \fBt_errno\fR unchanged.
Otherwise, a value of -1 is returned and \fBt_errno\fR is set to indicate an
error.
.SH VALID STATES
.sp
.LP
All.
.SH ERRORS
.sp
.LP
On failure, \fBt_errno\fR is set to the following:
.sp
.ne 2
.na
\fB\fBTBADFLAG\fR\fR
.ad
.RS 12n
\fIname\fR has an invalid value.
