.SH DESCRIPTION
.sp
.LP
The \fBdlpi_walk()\fR function visits all DLPI links in the current zone. The walk does not visit DLPI links in the non-global zones when called from the global zone. For each link visited, the user-supplied \fIfn\fR() function is invoked. The walk terminates either when all links have been visited or when \fIfn\fR() returns \fBB_TRUE\fR.
