The following parameter block
tests the link to a remote for a particular local link station (LS):
struct dlc_corr_arg
{
__ulong32_t gdlc_sap_corr; /* GDLC SAP correlator */
__ulong32_t gdlc_ls_corr; /* GDLC link station correlator */
};
The fields of this ioctl
operation are:
| gdlc_sap_corr | Indicates the GDLC SAP correlator of the target LS. |
| gdlc_ls_corr | Indicates the GDLC LS correlator to be tested. |
The DLC_TEST ioctl operation is selectable through the fp_ioctl kernel service or the ioctl subroutine. It can be called from the process environment only.
