NAME
t_sysconf - get configurable XTI variables
SYNOPSIS
#include <xti.h>
int t_sysconf(
intname);
DESCRIPTION
The
t_sysconf() function provides a method for the application to
determine the current value of configurable and implementation-
dependent XTI limits or options.
The
name argument represents the XTI system variable to be queried.
The following table lists the minimal set of XTI system variables
from
<xti.h> that can be returned by
t_sysconf(), and the symbolic
constants, defined in
<xti.h> that are the corresponding values used
for
name.
+----------+---------------+
|Variable | Value of Name |
+----------+---------------+
|T_IOV_MAX | _SC_T_IOV_MAX |
+----------+---------------+
RETURN VALUES
If
name is valid,
t_sysconf() returns the value of the requested
limit/option, which might be -1, and leaves
t_errno unchanged.
Otherwise, a value of -1 is returned and
t_errno is set to indicate
an error.
VALID STATES
All.
ERRORS
On failure,
t_errno is set to the following:
TBADFLAG name has an invalid value.
