.SH DESCRIPTION
.sp
.LP
The \fBnet_netidtozonid()\fR function maps the given \fBnetid_t\fR (used to represent an instance of \fBIP\fR) into the matching \fBzoneid_t\fR structure that is associated with it.
.SH RETURN VALUES
.sp
.LP
The \fBnet_netidtozonid()\fR function returns -1 if no mapping took place. Otherwise, it returns the \fBzoneid_t\fR structure currently associated with a \fBnetid_t\fR structure. For shared stack zones, the \fBzoneid_t\fR structure for the global zone is returned. 
.SH CONTEXT
.sp
.LP
The \fBnet_netidtozonid()\fR function may be called from user,  kernel, or interrupt context.
