The following parameter block
adds a functional address mask any time a service access point (SAP) has been
enabled via DLC_ENA_SAP ioctl. Multiple functional address
bits may be specified.
struct dlc_func_addr
{
__ulong32_t gdlc_sap_corr; /* GDLC SAP correlator */
__ulong32_t len_func_addr_mask; /* length of functional */
/* address mask */
uchar_t func_addr_mask[DLC_MAX_ADDR]; /* functional address */
/* mask */
};
The fields of this ioctl
operation are:
The DLC_ADD_FUNC_ADDR ioctl operation is selectable through the fp_ioctl kernel service or the ioctl subroutine. It can be called from the process environment only.
