t_sysconf(3C)

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.
