Get configurable XTI variables.
Standard library (libxti.a)
#include <xti.h>
int t_sysconf ( int name)
| 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 |
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.
On failure, t_errno is set to the following:
| TBADFLAG | name has an invalid value. |
