t_sysconf - get configurable XTI variables
#include <xti.h>
int t_sysconf(intname);
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 |
+----------+---------------+
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.
All.
On failure, t_errno is set to the following:
TBADFLAG
name has an invalid value.
In the TLI interface definition, no counterpart of this routine was
defined.

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.
TLI COMPATIBILITY
In the TLI interface definition, no counterpart of this routine was
