.SH DESCRIPTION
.sp
.LP
The \fBnet_getlifaddr()\fR function retrieves the address information for each
logical interface. Each call to \fBnet_getlifaddr()\fR requires that the caller
pass a pointer to an array of address information types to retrieve, and an
accompanying pointer to an array of pointers to \fBstruct sockaddr\fR
structures to which to copy the address information. See
\fBnet_lifgetnext\fR(9F) for an example on how to use this function.
.sp
.LP
Each member of the address \fBtype\fR array should be one of the values listed
here.
