DLC_DISABLE_SAP ioctl Operation for DLC

The DLC_DISABLE_SAP ioctl operation is selectable through the fp_ioctl kernel service or the ioctl subroutine. It can be called from the process environment only.

The following parameter block disables a service access point (SAP):

struct dlc_corr_arg { __ulong32_t gdlc_sap_corr; /* GDLC SAP correlator */ __ulong32_t gdlc_ls_corr; /* <not used for disabling a SAP> */ };

The fields of this ioctl operation are:

Field	Description
`gdlc_sap_corr`	Contains GDLC SAP correlator. The field indicates the GDLC SAP identifier to be disabled.
`gdlc_ls_corr`	Contains GDLC LS correlator. The GDLC LS identifier is returned to the user as soon as resources are determined to be available. This correlator must accompany all commands associated with this LS.
