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

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.

Error Codes

On failure, t_errno is set to the following:

TBADFLAG name has an invalid value.
