NAME

t_sysconf - get configurable XTI variables

SYNOPSIS



#include <xti.h>

int t_sysconf(
    int name);

DESCRIPTION

Parameters Before call After call
name x /

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

VALID STATES

All.

ERRORS

On failure, t_errno is set to the following:
[TBADFLAG]
name has an invalid value.

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.
